Calculating the amount of material for Rectangular Areas

a-1-soils-rectangular-areas-formula



Example: 40’ x 40’ x .33’ (4”) = 528 Cft³
Divide this by 27 Cft³ this equals 19.56 Cy³		   Inches = Feet
1 = .08’
2 = .17’
3 = .25’
4 = .33’
5 = .42’
6 = .50’
7 = .58’
8 = .67’
9 = .75’
10 = .83’
11 = .92’
12 = 1.0’

Calculating the amount of material for Circular Areas

a-1-soils-circular-areas-formula



Example: Diameter is 9 feet, you would like to fill 9” deep.
9’ x 9’ x π x .75’ = 190.76 Cft³ divide total by 27 Cft³ = 7.07 Cy³		   Inches = Feet
1 = .08’
2 = .17’
3 = .25’
4 = .33’
5 = .42’
6 = .50’
7 = .58’
8 = .67’
9 = .75’
10 = .83’
11 = .92’
12 = 1.0’
