Question

A driveway 18 ft wide and 36 ft. long is to be paved with concrete 3 in. thick. How many cubic yards of concrete are required?

Answer 1

6 yds^3

Explanation:

I find these easiest if you put all of the dimensions into yards and then multiply

18 ft = 6 yds

36 ft = 12 yds

3 in = 3/36 yds = 1/12 yds now multiply them together

6 x 12 x 1/12 = 6 yds^3
