You want to put a 2 inch thick layer of topsoil for a new 29 ft by 27 ft garden. The dirt store sells by the cubic yards. How many cubic yards will you need to order

Question

The store only sells in increments of 1/4 cubic yards

Answer 1

29x27x2/12 = 29x27/6 = 29x9/2 = 130.5 ft^3

130.5/27 = 4.8333... yd^3

sold only in 1/4 yd^3

4.8333...x 4 = 19.333...

20 1/4 yd^3 will be needed

which = 5 yd^3
