When building or repairing a wooden house, you need to have some knowledge, including information about the number of boards in one cube. For this, it is not necessary to be a genius in mathematics or to have a building education, it is enough only to be able to multiply and divide.
The timber has different types and types of wood, but the principle of calculation is approximately the same.

Calculation of lumber in 1 m3 according to formula
If you have knowledge of 3 components (be it a bar or board): width, height and length, you can easily calculate the amount and number of boards in the cube. Most often, for convenience of counting, a meter unit is used.
The formula of the volume (suitable for both the timber and the board)
V = a *b * c
Where:
V is the volume, m3,
a - Length, m,
b - Width, m,
c - Thickness, m.
Example:
V = 6 m * 0.1 m * 0.1 m
V = 0.06 m3
The formula for calculating the number of boards in 1 m3
Z = 1 / V
Z - This is the number of boards, pieces,
V - Lumber volume, m3.
Example:
Z = 1 / 0.06 m3 = 16 pcs.
Note that these calculations are approximate, they do not take into account such trifles as: the gap between the product, the type of processing, the allowance for length and other specific features
By these formulas it is impossible to know the number of unedged boards and slabs.
To avoid loading the head with a large number of formulas, you can use the tables below.

In order not to get on unscrupulous sellers, always try to calculate before buying whether or not 1 m3 is in the package, because some traders go for cunning, for their own sake and round up the volume.
Pay attention to the special table for calculating 1 m3 of timber. It allows you to quickly determine the amount and number of boards in 1 cube. In the column "size" 1 - thickness, 2 - width, 3 - length of one bar. Here the standard length is 6 meters.

According to the data presented above, you can easily find out how to calculate the number of cubes, boards and even square meters required for construction or repair, but some sellers still find tricks and profit from the ignorance of customers.
For example, take the volume of one unit, equal to 0.1944 m3, in order to find out the value, you need to multiply by the price of one cube, say 5300 rubles.

- Mirror panel on the wall - 55 photos of ideas in the interior
- Kitchen interior - 100 photos of modern design
0,1944 m3 * 5300 rub. = 1030.32 rubles.
But the seller, rounding up to three (and sometimes up to two) digits after the decimal point will have a good profit, but according to the rules, this reduction is possible with the purchase of a large amount of lumber.
In this case, we obtain:
0,2 m3 * 5300 rub. = 1060 rubles.
Yes, the difference is small, but with a large number of buyers an impressive amount is formed.
Also there is a small secret in the size of the boards, with a standard length of 6 m, the real can be from 6.1 to 6.2, in which case the remainder in the price should not be included.
