1 cubic yard covers 27/depth in feet square feet.
1 (cubic yard) = 46 656 cubic inchesIf the depth is 2 inches then the area it will cover is 46656/2 square inches = 23,328 square inches. Convert 23,328 square inches to square yards23 328 (square inches) = 18 square yards
To find the volume in cubic feet needed to cover 21,000 square feet, you would also need the height of the coverage area. The volume (cubic feet) is calculated by multiplying the area (square feet) by the height (feet). Without the height, it's not possible to determine the amount of cubic feet needed to cover 21,000 square feet.
