It depends how thin the cubic feet are. If they are 1 foot thick: 21,000 cubic feet. If they are 3 feet thick: 63,000 cubic feet will cover 21,000 square feet.

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.

373 cubic feet equals how many square feet at 1 inch deep?

To find the number of square feet covered by 373 cubic feet at a depth of 1 inch, you would first convert cubic feet to square feet.

Therefore, 373 cubic feet would cover 373 x 12 = 4476 square feet at a depth of 1 inch.
