Approximately 7,260 yards.
You need 6 yards of soil per 1000 square feet for 2"
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
Grass typically needs about 6 inches of topsoil to grow effectively.
To find out how much dirt is needed to fill a 12x18x36 planter box, first convert the dimensions into the same unit, if necessary. The volume can be calculated by multiplying the length, width, and height: (12 \text{ inches} \times 18 \text{ inches} \times 36 \text{ inches} = 7,776 \text{ cubic inches}). To convert this to cubic feet, divide by 1,728 (since there are 1,728 cubic inches in a cubic foot), resulting in approximately 4.5 cubic feet of dirt needed to fill the planter box.
10-1/2 cubic yards
10*13*3 = 390 cubic inches.
You will need 1500 cubic feet.
find the area of it 320 feet squared
