Given a one cubic yard of concrete in a block how much wood in sq ft would you buy to completely build a wood box around the 1 cubic yard of concrete?
1 yd = 3 ft
1 yd^3 = 9 ft^3
Let 'a' represent the length of the side of the box then:
a^3 = 9
a = 3 ft
The area of the box in sq ft us:
A = 6*a^2
A = 6*3^2
A = 54 ft^2
You will need 54 ft^2 of wood to build a wood bpx around the 1 cubic yard.
