Calculating Gallons

Estimating Gallons

Volume for Rectangular Pond

Width x Length x Depth = Cubic Feet

Cubic Feet x 7.5 = Gallons

Volume for Circular Pond

Radius x Radius x 3.14 x Depth = Cubic Feet

Cubic Feet x 7.5 = Gallons

Example for a Rectangular Pond

10’ x 15’ x 3’ = 450 Cu. Ft.

450 Cubic Feet x 7.5 gallons = 3375 gallons
