You would multiply out the two numbers to get 2835 cubic inches. Divide that by 1728 to get 1.64 cubic feet.
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 volume of gravel in cubic yards, first convert the depth to yards: 2 inches is 1/6 yard. Then, multiply the dimensions to get the volume in cubic yards: 5 yards wide x 28 yards long x 1/6 yard deep = 23 1/3 cubic yards. Since 1 cubic yard is equal to 1,296 square inches, multiply the volume by 1,296 to convert to square inches: 23 1/3 cubic yards x 1,296 = 30,158.22 square inches. Finally, divide by 9 to convert square inches to square yards: 30,158.22 square inches / 9 = approximately 3,350.91 square yards of gravel.
One cubic yard of gravel covers approximately 162 square feet when spread at a depth of 2 inches. This is calculated by converting the cubic yard to cubic inches (1 cubic yard = 46,656 cubic inches) and then dividing by the depth of gravel in inches (2 inches), resulting in about 23,328 square inches, which is equivalent to 162 square feet.
Coverting cubic feet into cubic inches first: 1 foot = 12 inches, therefore 1 cubic foot = 12 x 12 x 12 = 1 728 cubic inches 373 cubic feet therefore equal 1 728 x 373 = 644 544 cubic inches. Square root of 644 544 = 802.83598 Therefore 644 544 cubic inches in an object 1 inch deep would be 802.83598 inches square. 802.83598/12 = 66.902915 feet. To answer the question fully then: 373 cubic feet equals 66.902915 square feet at 1 inch deep.
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.
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**
One cubic yard covers 81 square feet 4 inches thick.
800 square feet x 1/12 x 3/4 = 50 cubic feet.
