Question

A building has a concrete foundation that’s 24” wide and 36” deep at all points. How many cubic yards of concrete are necessary to pour the foundation for the back wall which is 30” in length?

Answer 1

5/9 cubic yards

Explanation:

Just so L*W*H=24(36)(30)= 25920 cubic inches=25920 (1 in*1 in* 1 in)

36 in=1 yd

so

1 in =1/36 yd

do divide 25920 by (36*36*36)

The answer in cubic yards is 5/9 cubic yards
