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).
Best Answer: Calculate the volume of your pool, length X width X depth. Then multiply your answer by 7.5 to convert it to gallons. (7.4805194805 if you're pedantic!). Now look at your water bill and see how much they charge per gallon, and multiply your final answer by that. If your bill isn't detailed call your water company and ask them for the figures.
