Question

Scotty is planning to order 1 cubic yard of topsoil for his 15' by 24' garden expecting that if evenly spread, he would end up with 2 inches of topsoil. Is he correct? Explain.

Answer 1

2 inches = 0.1666 feet

15 x 24 x 0.1666 = 59.98 cubic feet

1 cubic yard = 27 cubic feet

59.98 is greater than 27 so 1 cubic yard of topsoil will not be enough
