Frequently asked questions
How do I calculate cubic yards?
Multiply length × width × depth, all in feet, then divide by 27. A 10 × 10 ft area 4 inches deep: 10 × 10 × 4/12 = 33.3 ft³, and 33.3 ÷ 27 = 1.23 yd³.
How many cubic feet are in a cubic yard?
27: a yard is 3 feet, so a cubic yard is 3 × 3 × 3 ft. It is also 0.7646 cubic meters (NIST Handbook 44).
How many square feet does a cubic yard cover?
324 ft² at 1 inch deep, 162 ft² at 2 inches, 108 ft² at 3 inches and 81 ft² at 4 inches: divide 324 by the depth in inches.
How much does a cubic yard weigh?
It depends on the material: about 1.45 short tons for sand, 1.42 for gravel, 0.80 for topsoil and 0.48 for lava rock (New Mexico EMNRD, from the BLM handbook).
How do I find the cubic yards of a circle?
Area = π × radius², times the depth in feet, divided by 27. A round bed 10 ft across and 4 inches deep: 3.1416 × 5² × 4/12 = 26.2 ft³, so 0.97 yd³.
