Question

You want to put a 6 inch thick layer of topsoil for a new 20 ft by 17 ft garden. The dirt store sells by the cubic yards. How many cubic yards will you need to order? The store only sells in increments of 1/4 cubic yards.

Answer 1

Here's your answer

Step-by-step explanation:

6 inches = 1/2 foot = 0.5 feet

The volume needed is V= 0.5 ×17 ×20 = 170 cubic feet

1 cubic yard = 3*3*3 cubic feet = 27 cubic feet

170 / 27 = 6.2962 cubic yards
