A mulch supplier sells by the cubic yard. To mulch 900 square feet at 3 inches deep, how many cubic yards are required?
a.About 2.8 cubic yards
b.About 5 cubic yards
c.About 8.3 cubic yards
d.About 27 cubic yards
Giải thích
Convert 3 inches to 0.25 feet, then 900 x 0.25 equals 225 cubic feet, divided by 27 equals about 8.3 cubic yards. Always convert the depth to feet before dividing by 27. Ordering the right amount avoids extra delivery trips.
