To raise 1 acre by 8 inches, you would need approximately 2,722 cubic yards of dirt. This calculation is based on the formula for volume of a rectangular prism (length x width x height) multiplied by the area of 1 acre in square yards (43,560 square feet).
806.66 Cubic Yards
1 acre = 43,560 square feet.1 cubic yard = 27 cubic feetA slab of soil 1-ft deep covering 1 acre has a volume of 43,560 cubic feet= 43,560 / 27 = [ 1,613 and 1/3 ] cubic yards
There are 43,560 square feet in an acre of land. To determine the volume of dirt in an acre, you would also need to know the depth of the dirt. If you assume a depth of 1 foot, then there would be 43,560 cubic feet of dirt in an acre.
hmm that's a tough one maybe 24' by 2' by 10 inches worth of dirt
1 foot by 36 sq feet = 36 cubic feet of dirt is needed
10-1/2 cubic yards
10*13*3 = 390 cubic inches.
You will need 1500 cubic feet.
24 x 8/12 = 16 cubic feet.
find the area of it 320 feet squared
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.
