Pool Volume Calculator: How Many Gallons Does a 20x4 Pool Hold?

Length x Width x Depth = Volume (in cubic feet)

Converting cubic feet to gallons:

1 cubic foot = 7.48 gallons

For a 20 x 4 pool, assuming a depth of 5 feet, the volume would be:

20 x 4 x 5 = 400 cubic feet

Converting to gallons:

400 cubic feet x 7.48 gallons / cubic foot = 2992 gallons

Therefore, a 20 x 4 pool with a depth of 5 feet can hold approximately 2992 gallons of water.
