Length times width gives the surface area of the pool. Multiplying that by the average depth gives the volume in cubic feet. Since there are 7.5 gallons in each cubic foot, multiply the cubic feet of the pool by 7.5 to arrive at the volume of the pool (expressed in gallons).
Convert volume in cubic feet to volume in gallons. One cubic foot of water contains 7.5 gallons. To find the gallons in a square or rectangular pool, multiply the volume in cubic feet times 7.5 to get volume in gallons. Round and oval pools require a different conversion factor, 5.9, to compensate for their curved shape.
