How many cubic yards of soil are needed to cover a 30 ft by 18 ft bed 6 inches deep?

a.About 5 cubic yards
b.About 10 cubic yards
c.About 20 cubic yards
d.About 2 cubic yards

Explanation

Volume in cubic yards equals length times width times depth in feet divided by 27. Here 30 x 18 x 0.5 equals 270 cubic feet, divided by 27 equals 10 cubic yards. Six inches must be converted to 0.5 feet before calculating.
