A cubic yard is a measure of volume (in 3-d space). A square foot is a measure of area (in 2-d space). The two measure different things and there is no sense in trying to convert from one to the other.
it will cover 3 cubic feet, or 9 feet, I am not sure how many square feet
1 cubic yard covers 27/depth in feet 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.
744 Square Feet
Here's the formula: 27 cubic feet = 1 cubic yard. 1 cubic yard will cover 324 square feet at a depth of 1 inch. 2000 square feet divided by 324 square feet = 6.2 yards (rounded). Another approach: 7 cubic yard X 324 square feet = 2268 square feet of coverage at a depth of 1 inch.
1 cubic yard of concrete fills 27/depth in feet square feet.
One cubic yard is equivalent to 27 cubic feet. To determine how many square feet it will cover at a thickness of 3 inches, convert inches to feet (3 inches = 0.25 feet). Then, divide the volume (27 cubic feet) by the thickness (0.25 feet): 27 ÷ 0.25 = 108 square feet. Thus, 1 cubic yard will cover 108 square feet at a thickness of 3 inches.
800 square feet x 1/12 x 3/4 = 50 cubic feet.
27 square feet Answer. 15 square metres at 3 inches thick.
1 cubic yard = 27 cubic feet.
One cubic yard of mulch will cover approximately 160 square feet at 2" deep, so you would need approximately two cubic yards of mulch to cover 271 square feet at 2" deep.
453.6 cubic feet=138.29 square feet
