# Volume Calculation

Use the measurements and formulas as described below to calculate the approximate volume of material needed for your project. This information provided is for reference only; actual product volumes needed may vary from your result.

## Calculating the amount of material for Rectangular Areas

Example:
40’ x 40’ x .33’ (4”) = 528
Cft³Divide 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

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’ |
