TIMBER:

>   How many pieces of timber in a cubic meter:
Example: How many pieces are there in 3 cubic meters of timber 50x200x6000 mm?
3 : 0,05 : 0,2 : 6,0 = 50 pcs

>   How many cubic meters is a unit of timber:
Example: How many cubic meters are 200 pieces of timber 25x100x3000 mm?
0,025 x 0,1 x 3,0 x 200 = 1,5 cubic meters (m3)

>   How many pieces of board are needed to cover m2:
Example: How many pieces of board 25x150x6000 mm are needed to cover an area of 18 m2?
18 : 0,15 : 6,0 = 20 pcs

>   How many m2 does one board cover:
Example: How many m2 of surface do 50 boards 25x200x4500 mm cover?
50 x 0,2 x 4,5 = 45 m2

>   How many running meters of board are needed to cover m2:
Example: How many running meters of inner lining board STV.12x95x4500(85) are needed to cover 34 m2?
34 : 0, 085 = 400 running meters

>   How many m2 does a running meter board cover:
Example: How many m2 does the floorboard HLL.28x120x4500(110) cover in the amount of 100 pieces or 4.5 x 100 = 450 running meters?
100 x 0,11 x 4,5 = 49,5 m2

BUILDING BOARDS:

>   How many m3 is a piece of plywood:
Example: How many cubic meters are 80 pieces of plywood 10x1250x2500 mm?
80 x 0,01 x 1,25 x 2,5 = 2,5 m3

>   How many boards are in m3:
Example: How many chipboards 10x1200x2600 mm are in 5 cubic meters?
5 : 0,01 : 1,2 : 2,6 = ca 160 chipboards

>   How many m2 will cover m3 of plywood:
Example: How many m2 of surface do 5 cubic meters of plywood 21x1525x1525 mm cover?
5 : 0,021 = ca 238 m2

>   How many m3 tiles are needed to cover m2:
Example: How many cubic meters of wind barrier boards 12x1200x2700 mm are needed to cover 80 m2 of exterior wall?
80 x 0,012 = 0,96 m3

>   How many boards are needed to cover m2:
Example: How many pieces of plasterboard 13x1200x2500 mm are needed to cover 60 m2 wall?
60 : 1,2 : 2,5 = 20 pieces

>   How many m2 covers a board:
Example: How many m2 of wall surface will 50 plasterboards 12.5x1200x2600 mm cover?
50 x 1,2 x 2,6 = 156 m2
