How can you know the volume of water in a swimming pool with rectangular shape?

Answer 1

If the pool is rectangular in shape then the formula is:

length X width x average depth x 7.5.

If the pool is circular then the formula is:

3.14 x 3.14 x pool radius (1/2 pool diameter) x average depth x 7.5.

If the pool has a shape other than these then it is a little more difficult.

For round pools you want the area of the circle x the height, or 3.14 x radius x radius x height, then convert feet to gallons by x 7.5.

A 24 foot by 4 feet deep pool holds 13,564 gallons.

Answer 2

To figure the volume, you must multiply width x length x height = volume measured in cubic feet..

Then you must convert the cubic feet to gallons per square foot.

The number of gallons per cubic foot is 7.48. So let's work a problem.

A pool is 10 feet high, 10 feet long and 5 feet wide.

10 x 10 x 5 = 500 cubic feet.

500 x 7.48 = 11,749.5 gallons.

If you are talking about a round pool, it is another calculation.

If your pool is 20 feet in diameter and 5 feet deep, your calculation is

oA = 3.1416(pi) x R2 x 10

314.16 x 5 feet = 1570.8 cubic feet.

If your pool has different depths such as most diving pools, then you use an average number for the height #.

example : 8 feet deep end up to 4 feet shallow would be an average of 6 feet. This is now your equation : 18' X 36' X 6' = 3,888 cubic ft.

3,888 X 7.48 = 29,085 gallons

Answer 3

L x W x avg. depth x 7.48
