Pool Volume - CPO® Math Tutorial

Ok. So we have cubic feet, or perhaps cubic meters. What good is it? The section on Gallons will provide a meaningful use for cubic feet.

Things to know about Pool Volume

LEARN HOW TO OPERATE YOUR PUBLIC POOL SPA FACILITY

Volume of any pool shape:

  • Volume is the space inside of an object. When talking about the volume of a
    pool, we express it in cubic feet. In metric terms, volume would be cubic
    meters.
  • Volume (V) = Area (A) x Average Depth (AD)
Volume is how many cubic feet can fit into an object. For the purposes of pools and spas,
all dimensions must be given in feet so as to calculate cubic feet. Therefore meters, yards,
and inches must be converted. From the Main Page:

  • Meters times 3.28 = feet
  • Yards times 3 = feet
  • Inches divided by 12 = feet (or fraction thereof)
Example:

  • (1) You have a pool with a length of 40 feet and a width of 20 feet.
    The shallow depth is 3 feet, and the deep depth is 7 feetWhat is the average depth?
    Pool Volume


    The formula is V = A times AD
    A = L x W
    AD = (D1 + D2) divided by 2
    A = 40 ft x 20 ft = 800 sq.ft.
    AD = (3 feet+ 7 feet) divided by 2 = 5 feet
    V = A times AD
    V = 800 sq.ft. times 5 feet
    V = 4,000 cubic feet (cu.ft.)
