A hole 40 inches deep by 12 inches wide has a volume of: 2.62 cubic 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 number of square feet covered by 373 cubic feet at a depth of 1 inch, you would first convert cubic feet to square feet. Since the depth is 1 inch, and there are 12 inches in a foot, 1 cubic foot would cover 12 square feet at a depth of 1 inch. Therefore, 373 cubic feet would cover 373 x 12 = 4476 square feet at a depth of 1 inch.
1 square foot = 144 square inches, so 100 square ft = 14400 sq inches. Multiply be 3 = 43200 cubic inches. I believe gravel is normally sold by the cubic yard. 1 cubic yard = (36 in)3 = 46656 cubic inches. So 43200/46656 = 0.926 cubic yards
1 cubic yard will cover 15 square yards at 3 inches deep.
200 cubic feet or 7.4 cubic yards
If the container is 1 inch deep, the area is 1 square foot.
One cubic yard covers 81 square feet 4 inches thick.
Here is my take: 1 gallon of water equals 231 cubic inches 1 square foot, 1 inch tall equals 144 cubic inches (12"x12"X1") 1 square foot needs 0.624 gallons to equal 1 inch of cover (144 cubic inched divided by 231 cubic inches) 16 square feet would require 9.975 gallons of water to be covered 1 inch deep. (16*0.624) **Runsky**
800 square feet x 1/12 x 3/4 = 50 cubic feet.
Two thirds of a cubic yard.
