How to Determine Pool Perimeter and Capacity

To Determine Pool Perimeter
Round Pools - 3.14 x Diameter
Oval Pools - 3.14 x A = (B-A) x 2
To Determine Pool Capacity
1). Determine surface area
Round Pools - R x R x 3.14
Kidney Pools - (A + B) x L x .45
Rectangle Pools - L x W

2) Multiply square footage by average depth to determine the approximate cube of the pool.
(Example: (3 ft. shallow end + 8 feet deep end) divided by 2 = 5.5 feet)

So, if we have a pool with a surface area of 512 feet, the cube would be 2,816 ft. (512 x 5.5 - 2816)

3) Multiply the pools approximate cube by 7.5 (gallons of water in one cubic foot)
Our pool with a cube od 2,816 ft would contain approximately 21,120 gallons (2,816 x 7.5 = 21,120)
