How many fence boards are in one cube? How many boards are in a cube: how to make calculations using various methods
Construction of a private house, cottage or any other building requires drawing up an estimate. It indicates the quantity of building materials and their cost. There are several methods that allow you to carry out the corresponding calculations. The board is a common material that is used everywhere. In order to determine how many boards are in a cube, you need to familiarize yourself with the calculation options and the nuances of this process.
The calculation of the cubic capacity of the board will depend on the degree of processing of the material, type and grade
How many boards in a cube: types of lumber and features of their calculation
The boards used in the construction of houses and other structures differ according to several criteria. First of all, the material from which they are made is taken into account. The technical characteristics of the product depend on the type of wood. Depending on the production method, these building elements are divided into types:
- edged;
Almost all wood products: edged lumber, planed, structural, etc. measured in cubes (cubic meters)
- unedged.
The first of them are of the highest grade and have correct form, since all their faces can be processed. In turn, unedged products are most often used to organize rough flooring, etc. The peculiarity of this material is that its side edges are not processed, they contain bark and have natural shape. This simplifies production unedged boards and affects its cost.
In order to answer the question of how to calculate the cube of a board, you must first decide which material will be used in the construction process. For example, it is easier to calculate the cubic capacity and cost of a trimmed part, since it has a geometrically correct shape.
For unedged products there are constant values, which are arithmetic averages. The table of boards in a cube is not always suitable in this case, since it takes into account the rounding of even edged lumber.
To purchase lining, you may need to make calculations to find out how much area of material is available in a cubic meter
Separately, it is worth mentioning building materials for finishing. This group includes floorboards, lining, block house and products that imitate timber. The design of these finishing parts includes special ribs and grooves necessary for tightly connecting individual elements to each other.
Helpful information! When calculating finished lumber, you need to focus only on the dimensions of the main part of the board. So the size lock connections is not taken into account, only numeric values product body.
Regardless of what type of material is used, a single formula is used to calculate the number of boards in a cube. The exception in this case is unedged products. Their calculation has its own characteristics, because such parts do not have all the faces necessary for calculation.
Formula for the volume of a cube: how many edged boards are in 1 cubic meter
Cube is geometric figure, which consists of 6 equal faces. Each of them is a square. To determine the volume of a given figure, you need to multiply 3 indicators together:
- length;
To determine the number of cut boards in 1 cube, you need to find out the volume of one of them by finding the product of three quantities, and then divide 1 m3 by it
- width;
- height.
In order to find out how many boards are in 1 cube, you need to multiply several values. The result is a mathematical expression that looks like this:
V = h x b x L, where:
h – height of the edged product (m);
b – element width (m);
L – length of one part (m).
Using this formula, you can determine the volume of 1 element. It is important to remember that when making calculations, it is necessary to convert the millimeter values of the product into meters. For example, in order to determine how many 25x150x6000 boards are in a cube, you will need to convert the numbers by multiplying them by 0.001. The finished mathematical expression after this transformation will look like this:
V = 0.025 x 0.15 x 6
The calculation algorithm is the same for all lumber of a certain group, regardless of their characteristics
As a result, it turns out that the volume of one wooden part equal to 0.0225 cubic meters (m³). Next, it remains to calculate how many pieces of edged boards are contained in 1 cubic meter. For this there is simple formula. It involves dividing 1 cubic meter by the volume of 1 board, which was obtained using the previous mathematical expression. Let's look at the calculation using an example:
1 m³ / 0.0225 m³ = 44.4
Thus, 1 cubic meter contains approximately (if rounded) 44 boards. After this, you can independently determine the amount of material needed for construction. specific design. And also at this stage you can draw up a general estimate indicating the price of edged boards per cubic meter.
To calculate the cost of 1 edged board, a mathematical expression is used, which implies multiplying the volume of 1 part by the price per cubic meter. Let's look at an example:
0.0225 x 8200 rub. = 184.5 rub.
The calculation showed that the cost of 1 product of the edged variety will be approximately 184 rubles. If the cost of 1 part is known, but you need to calculate the price of a cube of a board, you need to do the opposite manipulation. In this situation, you will need to divide the price for 1 product (184.5) by its volume (0.0225).
After some calculations, you can find out that 1 cubic meter contains approximately 44 boards
Note! Sometimes, especially when purchasing a small batch of boards, confusion occurs with decimal places. In some cases, lumber sellers specifically post prices calculated by rounding to the 3rd number. However, according to the law, this value is only suitable for large batches boards When purchasing several products, it is recommended to round according to GOST, namely to 0.000001 m³.
When calculating the amount of boards and the cost of lumber per cubic meter, it is advisable to take into account unplanned losses, which very often occur during construction. Therefore, it is recommended to buy edged products with a small supply (several pieces).
How many boards in a cube: calculation of unedged lumber
Calculating the cubic capacity of an unedged board has some nuances, since its shape is not correct. There is no such material rectangular section along its entire length, so it is used to organize temporary structures. The lower and upper surfaces of an unedged board must be processed along its entire length. Otherwise, this product is a side part of a log (slab).
The calculation of cubic capacity will depend on the degree of processing of the material, type and grade, for example, edged and unedged boards are calculated differently
To find the volume unedged lumber in 1 cubic meter, as well as its quantity, there are several methods. It’s worth noting right away that determining how many boards are in one cube is quite difficult if we are talking about incorrect geometric shapes. Therefore, the initial numbers obtained when calculating unedged parts will represent an approximate indicator.
Let's consider what methods are used to calculate the cubic capacity and quantity of unedged lumber:
- batch;
- piece;
- sampling method.
In the first case, you will need to load the lumber into a bag, which must have the correct shape. After laying it is necessary to measure the necessary indicators. Next, the standard procedure for determining the volume is carried out using the values obtained from taking measurements. This method is most common for products that do not have clear edges. For example, you can use it to calculate the cubes of a board 25x150x6000 in a cube (unedged).
For the width of an unedged board, when calculating, take the average figure
It is worth noting that in a mathematical expression of this type, a special coefficient is used (for width), which represents the average arithmetic number. Although this option is not fast, it allows you to answer the question of how to calculate the cube of the board.
The piece method involves the use of numbers corresponding to the average arithmetic values height and width of the edged product. These values are calculated in meters.
In order to find the arithmetic average, it is necessary to measure the board. The minimum width (at the narrowest point) and the maximum are measured. Next, both indicators are added and divided in half. After this, the same height manipulation is performed. The numbers obtained during the calculation must be multiplied by each other and by the length of the product.
Let's look at what this looks like as a mathematical expression:
(b max + b min) / 2 x (h max + h min) / 2 x L = V
When calculating large quantities of wooden building materials, the sampling method is used to determine the volume
Using this formula, it will not be difficult to determine the volume of 1 unedged element and answer the question of how to calculate the cubic capacity of the part. After obtaining this value, you can calculate and total boards per cubic meter. For such a calculation, you will need to use a formula similar to that for a trimmed part (the cubic meter is divided by the volume of the product).
Helpful information! When purchasing raw boards, you need to be careful. Sellers should use a factor that reduces the total volume to account for future shrinkage. To calculate wet coniferous products, 1 cubic meter must be multiplied by the number 0.96. In turn, the coefficient for hardwood is 0.95.
The last method that allows you to determine the volume of lumber and its quantity in 1 cubic meter is the sampling method. It is used when calculating large quantities of wooden building materials. The essence of this method is that several boards are selected from the total mass. Then the parts are measured and calculated according to the piecemeal method. The resulting numbers are multiplied by total number parts in the batch.
An unedged board has a large spread in width at opposite ends, so when calculating an unedged board you need to substitute the average width into the formula
How many boards in a cube 50x150x6000 in a cube: calculation
As an example, you can take an unedged product with dimensions of 50 by 150 by 6000 mm. First, convert millimeters to meters. Some people don't know how many millimeters are in 1 meter. To convert, you will need to multiply the required number in mm by a factor of 0.001. In its finished form (with substituted values), the formula will look like this:
(0.155 + 0.145) / 2 x (0.055 + 0.045) / 2 x 6 = V
After addition and division by 2, we obtain the arithmetic average of the width and height of the unedged part. Thus, the formula takes on a more understandable, standard form:
0.15 x 0.05 x 6 = 0.045
This is how a calculation is made, the result of which is to find the volume of 1 board. To determine the number of products in 1 cubic meter, the same formula is used as in the case of a trimmed analogue.
Before determining how many 50x150x6000mm boards fit in 1 cubic meter, you need to convert millimeters to meters
If necessary, you can calculate the area of one board. Most often this is required when the manufacturer indicates the price per square meter, and not per cubic meter. The area formula involves multiplying the width of a part by its length. In this case, it is important not to make a mistake and remember to convert millimeters to meters.
In order to determine the cost, the same formula is used as in the case of edged lumber. You just need to multiply the volume of 1 part by the value that corresponds to the total price of the cube. This is how the calculation of cubes in a cube of a 50x150x6000 board is performed.
Calculating the board using an online calculator
Perhaps the simplest method (along with the lumber cubature table) by definition exact value volume and quantity wooden planks– online calculator. It is a program with specified algorithms that allow you to calculate all the necessary values of lumber. This method makes it possible to calculate not only edged boards, but also other types of these products.
Note! In order to avoid the possibility of errors when calculating material using an online calculator, you should immediately indicate for which board the measurement is being used.
To avoid mistakes when calculating material using an online calculator, you need to indicate for which board the measurement is being used
The process itself is quite simple. First, you need to find a calculator on one of the specialized sites using the search bar of your browser. Next, you will need to enter the necessary indicators in the appropriate cells. The cube board calculator will do the calculations on its own.
This method is popular and allows you to quickly and accurately determine all the necessary values of lumber. When using the calculator, it is recommended to check the accuracy of the filling several times. In case of an error, the calculation will be performed incorrectly, which can lead to serious discrepancies in the final figures.
How many boards are in a cube: table (6 meters)and tips for its use
The last method to determine the quantity and cubic capacity of wooden products is to use a special table. This method is very convenient as it does not require lengthy calculations. All that is needed is simply to find the desired value in the table using the original data (width, height and length).
In order to quickly find the correct answer to the question, how many boards are in one cube, the table is suitable the best way. However, experts point out one drawback of this method: numbers corresponding to cubic capacity or quantity are often rounded. Therefore, if you need to perform the most accurate calculation, it is recommended to carry out all the calculations yourself.
Volume of edged board in cube:
| Board dimensions, mm | Length, m | Volume 1 piece, m³ |
| 50 to 200 | 6 | 0,06 |
| 30 to 100 | 0,018 | |
| 20 to 150 | 0,018 | |
| 30 to 150 | 0,027 | |
| 20 to 200 | 0,024 | |
| 30 to 200 | 0,036 | |
| 25 to 100 | 0,015 | |
| 40 to 100 | 0,024 | |
| 25 to 150 | 0,0225 | |
| 40 to 150 | 0,036 | |
| 25 to 200 | 0,03 | |
| 50 to 100 | 0,03 | |
| 40 to 200 | 0,048 | |
| 50 to 150 | 0,045 | |
| 20 to 100 | 0,012 |
In addition, before starting to search for the desired value, it is advisable to make sure that the length of the lumber matches. Tables can be different, containing information about the cubic capacity of boards with a length of 3, 4 or 6 m. Today the most common are wooden crafts, the length of which is 6 meters. How many boards are in one cube? The table that allows you to determine the quantity of lumber also uses rounded values.
Using the tables, you can determine the approximate number of boards in a cube without resorting to calculations
Do not forget that the board can be made of different breeds tree. Therefore, before you start using the table, it is recommended to make sure that you have selected the required type of lumber.
How many boards are in 1 cube: table (6 meters):
| Board dimensions, mm | Length, m | Number of pieces per 1 m³ |
The good thing about the tabular method is that it does not require calculations or self-filling of dimensional and other values of lumber to obtain an answer. It is suitable for determining cubic capacity, and also allows you to answer the question of how many boards are in a cube. The table is ideal for calculating large batches of products.
Prices of edged boards per cube: 50x150x6000and other varieties
Today you can find many types of lumber on the construction market. All of them are differentiated not only by size, but also by the type of wood from which they were made. The cost of these products is also influenced by production technology and their purpose. In order to find out how much a board cube costs, you need to familiarize yourself with all the varieties of these parts.
1st grade lumber, made in accordance with technical specifications, costs on average about 7,000 rubles. per cube
The most popular in the construction of private houses, cottages, and other structures is the classic edged board. It can be 1st or 2nd grade. The first option is more expensive because it has higher technical characteristics and durability.
Helpful information! The price for a 1st grade edged board is approximately 7,500 rubles. for 1 cubic Products that belong to a lower quality group cost about 4-6 thousand rubles. for 1 m³.
The width and height of the boards, as a rule, does not affect their cost. This is due to the fact that in a cubic meter, regardless of the dimensions of the wooden lumber, there will be the same number of parts. In the sense that for the same price you will get 44 edged boards 25x1500x6000 (price per cube: 7500 rubles) or 22 parts 50x150 having the same length.
Separately, it is worth mentioning edged boards made in accordance with technical specifications (TU). Lumber of this type costs on average about 7,000 rubles. per cubic meter Such boards are distinguished by good quality characteristics and can be used in the construction of various structures.
Construction board is often used in interior design
Unedged products are cheaper because they are of lower quality. Their cost is calculated using average values. The price of unedged lumber ranges from 4 to 5 thousand rubles. However, they are not recommended for construction. It is better to use higher quality lumber, for example, edged boards 40x150x6000 (price per cube: 7500) or similar products with other dimensions.
When purchasing wooden lumber, you need to pay attention to some points. For example, the board must be level. The curvature of a product most often indicates that the technology was violated during its production. Such parts are not used in construction because they do not have the required quality.
How much does a cube of board weigh? When purchasing this building material, you should consider its weight. For example, an edged board made from dry spruce weighs 450 kg (1 cubic meter). 1 m³ of raw product has a mass of 790 kg. Dry pine weighs 470, and wet - 890 kg. This knowledge will be needed when transporting products.
When choosing a board, you need to check whether there are knots on it, since their presence greatly disrupts the internal structure and leads to a decrease in strength characteristics
When choosing lumber and calculating it, you must be careful. The board should not have cracks, chips or other defects. Allowed small cracks, however, it is recommended to buy a whole one, quality product, corresponding to GOST. You should also pay attention to the presence of knots. This is due to the fact that they negatively affect the strength of the wooden part. The choice of calculation method depends on the specific case. If necessary, you can always use the services of specialists who will help you perform the correct calculations and draw up an estimate.

Video: How many boards in a cubic meter. Memo to the developer
It would seem, why do you need to know how many boards there are in one cubic meter? After all, during large-scale construction, boards are sold in “m3” anyway and payment is made precisely for the volume, and if only a few pieces are needed, then the cost is determined by linear meters. Still, you should understand how such a calculation of material is made.
At proper organization At the first stage of work there is always such an item as planning. And not only the design and features of the future structure, but also material costs. Consequently, if, in accordance with the project, 40 boards are required, then, taking into account defects or inaccuracies, you will have to buy - with a reserve - 45 pieces. For this, you should calculate how many “cubes” you need to purchase and add a few more blanks to them.
Why?
Firstly, the number of boards in 1 m3 depends on their parameters (thickness, length, width). Naturally, for each size their number in the “cube” will be different.
Secondly, when carrying out any work, be it a new building or renovation, they are always used different boards. For rafter system– some, for floors – others.
Third, buying extra material is a waste of money. Of course, the boards will come in handy later, but they need to be stored somewhere. And not just leave it on the site and then end up with “rot,” but provide the proper conditions. And given that we have never had a shortage of wood, is it worth purchasing significantly more than we need?
Fourthly, time factor. What if there are not enough boards when purchasing in cubic meters? What, stop work, look for freight transport, waste time going to places of sale?
And fifthly, You should not hope that the Seller will answer such a question. IN best case scenario– will offer to count the boards in the stacks yourself, if interested. At worst - on purpose or out of ignorance - he will deceive.
We offer you a table with ready-made data:
It only has 3 columns. The first indicates the dimensions of the workpieces (in “mm”), the second – their quantity per 1 m3, and the third – the volume of 1 board (also in “m3”). There is nothing complicated. You just need to find the corresponding line, and the answer to your question is received.
By the way, it's very convenient. If you multiply the entire required number of boards by the volume of one, it will become clear how many “cubes” you will have to purchase, which means how much money you will have to spend. This is exactly what a prudent owner should do. And you don’t need tables, just use a calculator.
This table provides data for both edged and unedged boards. In addition, there are calculations for, which is also often used in construction or repair.
In principle, this is quite enough.
Note
All of the above is true if you purchase edged boards. But it also costs more. It is more economically profitable to take unprocessed material if you have the opportunity to trim it yourself. But in this case it is necessary to apply a coefficient when calculating. Experts believe that 20–30 percent of unedged lumber will go to waste. Consequently, from 1 “cube” of finished boards you will get fewer.
Any construction or renovation work with wood requires painstaking calculation required quantity this building material. How to correctly calculate how much to buy of this material so as not to spend extra money and have enough for everything planned? Below is the formula and rules for calculating cubic meters of wood, which will help eliminate even the slightest errors!
What types of lumber are there?
Perhaps every person understands what lumber is. This is a tree that has already been sawn using special equipment.
The process of preparing lumber is always the same:
- Timber (round timber, i.e. logs) is brought to the sawmill;
- Next, this primary timber is sorted according to the areas of subsequent processing in order to ultimately obtain wood building materials required size(length) and cross-sectional area (width + thickness).
You should know that timber and any type of lumber will be measured in cubic meters. According to construction and mathematical standards, a cubic meter is a volumetric square, the length, width and height of which is taken to be one meter.
In order to accurately determine whether there are enough wood building materials for a specific construction task, it is necessary to take into account the dimensions of the resulting edged board and the features of its primary wood processing.
Edged timber
This is the most popular lumber for construction or renovation, which can be of various lengths and cross-sectional sizes. If you know these cutting parameters, it is easy to find the number of boards in a cube.
For example, we received 25 boards 50 x 150 x 6000 mm. To calculate how many cubes this is, you can use a special table. There are only three columns here, according to the readings of which it is easy to calculate how many boards are in one cube. Since we have 25 boards, it’s easy to find out what cubic footage it is: divide 25 by the resulting value (how many boards are in 1 cube in a table of 6 meters).
Planed timber
Unlike edged timber, which has natural humidity, the planed timber is qualitatively dried. As a result of drying the timber, its volume and weight change slightly (decreases):
- If you use undried wooden lumber in construction, then when it dries, the surface may change its shape (the timber twisted or bent).
- The quality and wear resistance of the structure as a whole will depend on how much the building material weighs.
Another difference between planed timber and other types of lumber is considered to be a strict pattern in the original dimensions: the cross-sectional length of the timber should not exceed 2 times the width.
Planed block
By construction GOSTs there is a certain indicator that distinguishes timber from timber. This is the width of the section: if this parameter is more than 100 mm, then we have a beam, and if the width of the section is less than (or equal to) 100 mm, we are dealing with a beam.
Edged block
Edged block (similar to edged timber) is freshly sawn (or without high-quality drying) lumber.
The difference between edged or planed timber/timber is almost arbitrary, because change the width of the material by 2 - 3 cm (and therefore change the status of this material) at the sawmill without any problems.
Professional builders choose timber for the intended use, considering only 3 signs:
- The type of wood from which the timber is made;
- Drying time for this log;
- Peculiarities building structure(weight load), for the construction of which building materials are selected.
Edged board
This is a type of lumber with certain dimensions: the width should be 2 times greater than the thickness of the section. Load bearing capacity of such building material is less than that of timber.
Because their purpose is appropriate:
- Interior work (floor, roof, walls);
- Exterior improvements (fences, siding, construction of outbuildings, etc.).
Floor board
According to dimensions and intended purpose, there are different kinds floorboard (or lining).
Today the market building materials offers the following types of lining that copes well with covering any surface:
- Parquet - extremely high quality and the practical properties of this type of flooring are ensured by an internal structure of 3 layers: spruce, wood-fiber coniferous species and decorative from fruit trees, ash, oak.
- Terrace - consists of natural wood+ some polymers. It is characterized by high tolerance to humidity, temperature fluctuations, and light.
- Sexual normal is pure wood material. Pine linings are used for arranging floors, walls, ceiling coverings in residential areas. Linings made from aspen or linden are ideal for a bathhouse; larch linings are used for arranging street buildings (gazebos, terraces, etc.).
Based on quality, lumber for flooring is further divided into classes:
- Higher (or selected) is used only for elite buildings with extremely high wear resistance and reliability;
- The first and second are applicable for the construction of ordinary housing;
- The fourth is exclusively suitable for outbuildings.
How to measure
Calculation sufficient quantity lumber is a responsible task. To calculate how many pieces should be purchased to carry out repairs on a specific floor or wall area, you should know cubic meter as much as this lumber.
The task is not difficult, but pedantic, and begins with calculations on one board:
- The width, length and thickness of a unit of lumber are indicated in millimeters, which should be converted into meters;
- Multiply the obtained values (width x length x thickness) - this is the cubic footage of the board/beam.
Now, in order to estimate how many such boards/beams are in a cube, you need to divide 1 m 3 by the resulting product of the external dimensions of the building material and round to the nearest whole value. This will be the desired result.
How many boards in a cube: timber table
In order not to waste time on measurements/calculations, you can use a ready-made table. Here, based on the known dimensions of the timber, it is easy to calculate how much timber is in 1 cube and what is the volume of one timber.
| Beam size (mm) | Number of beams 6 m long in 1 m 3 lumber | Volume of 1 beam 6 m long |
| 100 x 100 | 16,6 | 0,06 |
| 100 x 150 | 11,1 | 0,09 |
| 100 x 200 | 8,3 | 0,12 |
| 150 x 150 | 7,4 | 0, 135 |
| 150 x 200 | 5,5 | 0,18 |
| 150 x 300 | 3,7 | 0,27 |
| 200 x 200 | 4,1 | 0,24 |
How many boards are in 1 cube: board table
There is a similar table for boards: knowing in advance (or measuring with your own hands) original dimensions, it is very easy to find out the volume of a unit of this building material and how many boards of that size are in the cube.
| Board size (mm) | Number of boards 6 m long in 1 m 3 lumber | Volume of 1 board 6 m long (m 3) |
| 25 x 100 | 66,6 | 0,015 |
| 25 x 150 | 44,4 | 0,022 |
| 25 x 200 | 33,3 | 0,03 |
| 40 x 100 | 62,5 | 0,024 |
| 40 x 150 | 41,6 | 0,036 |
| 40 x 200 | 31,2 | 0,048 |
| 50 x 50 | 67 | 0, 015 |
| 50 x 100 | 33,3 | 0,03 |
| 50 x 150 | 22,2 | 0,045 |
| 50 x 200 | 16,6 | 0,06 |
| 50 x 250 | 13,30 | 0, 075 |
Formula for calculating a board in a cube in squares
To calculate surface area, only two indicators are used: length and width. Therefore, to count required quantity lumber for work, the cubic capacity of lumber should be converted to quadrature and compared with the surface area.
It's easy to do: 1 m 3 divided by the thickness of the selected unit of building material.
Formula for calculating a board in a cube in pieces
To determine how many boards of a given size are in 1 cubic meter, you should:
1 m 3 / board volume (i.e. length x width x thickness)
Formula for calculating the volume of a board
Volume is a three-dimensional quantity. To calculate the volume of a board, take the product of width, thickness and length. But the situation becomes simpler if you take a meter-long beam or board. In this case, we multiply only the remaining two quantities: thickness and width of the section.
How many boards are there in a cubic meter? Memo to the developer
When implementing construction work for the construction of a residential building, a specialist must perform big number various tasks, one of which is: drawing up and calculating the estimated cost to the final finishing of the premises of a residential building. It is mandatory to calculate the required amount of various building materials, which is quite difficult to do. Therefore, such knowledge - how many boards are in a cube - has a very important for a specialist who is engaged in the construction of a residential building and wants to complete the work as efficiently and quickly as possible.
Buying club: existing types of boards
To calculate exactly how many board pieces are in a cube, you will need to know not only what exactly a board cube means, but it is worth understanding important point that there are different types of boards and what is possible to purchase on modern market for performing various construction works. It should be noted that the cube of almost all materials, regardless of the type of material, is calculated in the same way, that is, according to one specific method. The types of boards have no influence on the calculation of the cubic capacity of this building material.
Non-grooved types of lumber are: timber, various edged boards, as well as unedged boards (they are an exception when calculating cubic capacity, because this process occurs a little differently). Tongue-and-groove types (which have special grooves for making joints) include: modern lining, blockhouse, flooring material, as well as imitation natural timber. When you choose a tongue-and-groove type of building material for purchase, then you will need to pay attention to the fact that when making calculations, only the working width of the board without a tenon is used. If we talk about a blockhouse (imitation log), then when calculating the cubic capacity, only the thickness at its highest point is taken.
How many boards are in 1 cube: performing the calculation
Any person, even from his school days, understands how cubic capacity is calculated. For this procedure, it is necessary to calculate quantities such as: length, width and height. A similar principle is used to calculate the cubic capacity of 1 board. When performing such calculations, it is recommended to convert all available values into meters. The cubic capacity of 1 board, which has a cross-section of 150x20 mm. and a length of 6 m, is calculated as follows: 0.15 multiplied by 0.02 and 6, so that the cubic capacity of this board will be 0.018 cubic meters.
Let's apply the volume formula V= L*h*b (where L is length, h is height, b is width).
L= 6.0; h= 0.02; b= 0.15.
Thus, V= 6.0*0.02*0.15 = 0.018 m3.
To determine how many boards are in one cube: divide 1 m3 by cubic capacity (the volume of one board).
1 m 3 / V = N pcs.
1 m 3 / 0.018 m 3 = 55.55 pcs.
Thus, the number of boards in one cube is 55.5 pieces.
Finding out the cost of a certain type of board when the values of its volume is known is quite easy: 0.018 multiplied by the price of 1 cubic meter. When 1 cube of a certain type of board costs, for example, 5,500 rubles, then the cost will be 99 rubles. At this point in the calculation, there is some trick of sellers and managers in construction stores, because the cubic capacity of the material is rounded to some integer values.
Such rounding can lead to such a moment that the price of 1 board (when 1 cube costs 5500) will be completely different values. In addition to all this, it should be noted that various boards for construction, which have a nominal length of 6 meters, the actual length is 6.1 - 6.2 m, which is not taken into account when selling this building material. This also applies to the purchase significant number boards This can be seen quite clearly if we use a 150x20 mm board as an example. The number of boards in a cube is a value of 55.5 pcs. But, in a cube they count 55 pieces, which when performing the calculation will have a value of 0.99 cubic meters. In fact, it follows from this that the overpayment for 1 cubic meter of this popular building material can amount to 1% of the real price. For example, 5500 instead of 4995 rubles.
To calculate the cubic capacity for a continuous type of board, slightly different methods are used. When we are talking about buying 1 board, then measuring its thickness, as well as the total length, is carried out in the same way as when choosing edged building material. In this case, the average width is taken for calculations - between great value and small.
For example, when the width of the board at one end is 25 cm, and at the other 20, then the average value will be approximately 22 centimeters. When it is necessary to calculate the volume of a significant number of similar boards for construction, then you will need to lay them out so that the wide one does not differ from the narrow one, more than 10 cm. The main length of this material in the laid out stack should be approximately the same. After this, using a regular tape measure, an accurate measurement is made of the height of the entire existing stack of boards, and the width is measured (approximately in the very middle). The result obtained will then need to be multiplied by a special coefficient, amounting to a value from 0.07 to 0.09, directly dependent on the existing air gap.
How many boards are in 1 cube: special tables
To calculate the exact number of boards of a certain width and length in 1 cubic meter, various tables are used. Below are several such specialized tables, which indicate the cubic capacity of the common and in demand types of this material today. Calculate the volume of various boards having various sizes, for example, material for constructing a fence on your site, you have the opportunity to independently use the existing formula, which is presented above.

Table of the amount of unedged boards in 1 cubic meter
Meters are linear, square and cubic. Starting a big construction project or even small repairs, you should clearly understand these terms. The ability to correctly convert the amount of certain materials into linear or cubic meters will serve an excellent purpose in preliminary calculations of the cost of planned repairs or construction. For example, clearly understanding how much square meters in one roll of wallpaper, you can quickly calculate the amount required to cover a room or the entire apartment.
Calculations can be made in cubic meters, square or linear meters
If the upcoming repair or construction involves the use of wooden materials, you need to thoroughly study the calculations from linear meters in cubic, since prices can be presented on the market both per unit of material and per cubic meter. The amount of timber in a cube varies and depends on its cross-section. The easiest way to find out how many boards are in a cube is a table, but if it is not nearby you will have to remember the formulas.
What is a cubic meter
A cubic meter (abbreviated m³) is a unit of volume and is equal to the volume of a cube with an edge length of 1 meter. In accordance with GOST 8486-86 wooden materials must have measurable cross-sectional dimensions and lengths, so that you can easily calculate the number of boards included in a cube of material.
To determine the dimensions of the section, it is necessary to step back from the end of the beam at a distance of at least 10 cm and measure the width and height of the beam. By multiplying these values by each other, you get the cross-sectional area of the beam, multiplying it by the length to get the volume of one beam. By calculating the number of beams in one cubic meter, you can easily navigate between the cost of one beam and one cube of beams.
A cubic meter is equal to the volume of a cube with an edge side of 1 m
Calculation of lumber for construction before purchasing it
Of course, the easiest way is to come to the developer to explain what you want to see in the final version and agree to the proposed project. But, if you independently understand the calculations of the required amount of lumber, then even at the stage of discussing the cost of materials and work on building a house, you can get an idea of how realistic the prices are offered by the construction company.
Many developers calculate the required amount of material in cubes, some count individually, taking the standard length dimensions as 6 or 12 m. A clear understanding, for example, of how much timber is in a 150x150x6000 cube will protect you from overpayments.
Standard timber 0.15x0.015x6 meters
The procedure for calculating the amount of timber in a cube
Despite the same principle of calculations, there are certain nuances in determining the cubic capacity and quantity of various lumber.
1. Basic formulas for calculating the number of bars in a cube
To determine how many boards are in a cube, with beams of a certain section, you need to know three measured parameters: length, width and height. First you need to calculate the volume of one beam using the formula V = a * b * l (here V – volume, m³; a – height, m; b – width, m; l – length, m)
Beam parameters: length, width, height
How many pieces of timber in a cube is determined by the formula:
Where, A is the amount of timber in a cube, pcs.;
1 – one cubic meter, m³;
V – volume of one beam, m³.
2. How to determine how many pieces are in a cube of 100x150 timber
In price lists construction companies for convenience, indicate the cross-section of the beam, that is, its width and height, for example, 100x150. Where 100 is the width indicated in millimeters, and 150 is the height. The length is most often 6 meters, or 6000 mm.
The volume of timber 100x150x6000 will be 0.09 m³.
V = 0.1 m * 0.15 m * 6 m = 0.09 m³. Here 0.1 is the width, m; 0.15 – height, m; 6 – beam length, m.
In this case, how much material will “fit” in one cubic meter can be found by dividing the cubic meter by the volume of one beam:
Where, 1 – one cubic meter, m³;
0.09 – calculated volume of one beam 100x150x6000, m³.
The characteristic cross-sectional shape of the timber is 100x150
This way you can easily calculate how many pieces of timber are in the purchased volume of material by multiplying the number of pieces by the number of cubes. For simplicity and speed of calculation, you can use the table: how many timber in a cube is 6 meters table.
3. How many edged boards are in 1 cube
The situation is similar in calculating the amount of edged boards in 1 cubic meter of wood. For example, the board used has the following parameters 100x25x6000 (width, height, length).
The volume of one board will be 0.015 m³.
V = 0.1 m * 0.025 m * 6 m = 0.015 m³
Quantity in 1 cube:
That is, a cubic meter contains at least 66 boards. When purchasing a cube of 100x25x6000 edged boards, you should get 67 pieces, rounding up. For example, when buying three cubes you should get at least 201 pieces, and when buying six - 401.
4. How many tongue and groove floor boards are there in 1 cube?
tongue and groove floor board for better installation It has a groove along its entire length on one side and a tenon on the other. When calculating the volume of one board, its length, height and net width are taken into account, that is, the width without taking into account the protruding tenon. For example, the size of the board reflected in the figure below is 28x90 mm.
tongue and groove floor board
If the board is 6 meters long, its volume will be:
V = 0.09 m * 0.028 m * 6 m = 0.01512 m³
Quantity in 1 cube:
5. How much wooden lining in 1 cube
The design of the lining vaguely resembles tongue and groove board floor. It also has a tongue-and-groove connection and ventilation grooves, but the front side of the lining can have bevels, curves and even a convex surface, imitating timber.
For the calculation, the “net” width is used, that is, the size without taking into account the tenon; the maximum value in the cross-section of the board is taken as the height.
Types of lining with a clear example measuring the width and height of the board
The most common lining size is 100x14. With a board length of 6 meters, the number of linings in one cube will be at least 119 pieces:
Volume of one board:
V = 0.1 m * 0.014 m * 6 m = 0.0084 m³
Quantity in 1 cube:

What else to consider when counting lumber
One of the nuances in the production of lumber is their technological length, that is, the declared six-meter board in practice turns out to be 5-10 cm longer. This deviation is called technological and is not taken into account when calculating the linear meters of the board. The seller under no circumstances has the right to add them to the total length of the board.
When purchasing timber of a certain cross-section, it is important to measure the parameters upon acceptance or loading, since the slightest deviation of even 1 cm leads to huge losses, especially with large purchase volumes.
In addition to volume, it is important to remember the weight of the purchased material, which depends on the density of the material and humidity.
An example of calculating the weight of a beam based on the known density of wood (for materials of different moisture content, you must substitute the appropriate values instead of 860)
Tables for quickly calculating the volume of timber
Below are cheat sheets to quickly find out how much timber is in a cube - the table contains not only the quantitative values of units of material per cubic meter, but also the volumetric values of timber of different sections.

Features of lumber storage
To build a house made of wood, it is important to properly store the material so that its humidity is within 12%; if the humidity is higher, the shrinkage of the building will be slower.
Here are a few rules to remember when storing lumber:
The storage area must be level and dry.
To prevent moisture from entering the site onto the site, pallets are placed under the first layer of material, which can be replaced with scraps of boards or sleepers.
The distance between individual products should be maintained at least 2 cm for better air circulation.
After 1-2 rows, crossbars are placed across the length, which can be the same cuttings of boards.
If it is not possible to erect a canopy over the storage area to prevent precipitation from entering, the stacks are covered with film, excluding wrapping the ends, so as not to create a greenhouse effect inside.

Conclusion
Knowing the rules for calculating the required volume of building materials will help you save time and money, or simply make sure that the developer is conscientious. Therefore, if you do not have the skills to quickly convert one quantity into another, then when discussing the required amount of building materials you should keep with you at least a cheat sheet in the form of a cube table.
