You already have a square yard of topsoil, so how does 20 inches of depth get you the volume of topsoil? There are 36 inches in a yard, and you have 20 inches of topsoil depth that's 20/36ths of a yard of topsoil depth. That's 0.555... or about 0.56 yards. The volume of topsoil is 1 yard by 1 yard by 0.56 yards, or about 0.56 cubic yards of topsoil.
1 acre = 4840 square yards, so 1 acre 20 yards deep = 4840*20 = 96,800 cubic yards.
3,226,666.7 cubic yards.
Three acres three inches deep is 403.33 cubic yards.
An acre is an area, a cubic yard is a volume, the question has no meaning
1000000 cubic yards
1,000,000 cubic yards.
1 cubic yard = 27 cubic feet1 acre = 43,560 square feetVolume = (6 x 43,560) x (3) = 784,080 cubic feet = 29,040 cubic yards
This is the worth math I've ever seen! 1 acre = 43,560 SF, take the square root of 43,560 to give you the base numbers of the acre = 208.71 feet for both the height and width of an acre to get square feet of an acre. Divide 208.71 / 3 = 69.57 yards for the height and width of the acre. Multiply 69.57 x 69.57 = 4,840 square yards in an acre. A cubic yard is simply 4,840 square yards dug down 3 feet or one yard. So one acre has 4,840 cubic yards of dirt if you only dig down 3 feet. If you dig down 6 feet that doubles and so on. One acre would have 48,400 cubic yards of dirt if you dug down 30 feet or 10 yards. Using a one cubic yard example if you removed one cubic yard of dirt from an acre you would have 4,480 cubic yards of dirt, and one cubic yard of dirt weighs approximately 1.3 tons so once cubic acre weighs 1.3 x 4,840 acres = 6,292 tons.
The question is impossble. We have the volume of a cubic yard and a flat area of a square feet. That can never come together. Bananas are no apples.
1 acre = 43,560 square feet1 cubic yard = 27 cubic feet1 inch = 1/12 foot1 acre x 1 inch = (43,560 x 1/12) = 3,630 cubic feet = (3,630 / 27) = 134 and 4/9ths cubic yards
one acre = 4840 sq yd and 3 feet = 1 yard 4840 x 1 = 4840 cu yds
3,495.6 cubic yards.
62/3 cubic yards for every 1-foot deep. 5 cubic yards for every 9-inches deep. 31/3 cubic yards for every 6-inches deep. 5/9 cubic yard for every 1-inch deep.
