How many gallons of water does it take to fill a swimming pool that is 5'x30'x4'?
The formula for figuring out the amount of gallons is on the back of pool chemical containers. I am not sure what the formula is for an oval.

If the pool floor slopes uniformly from end to end, the average depth can be found by adding the deepest and shallowest depth measurements and dividing the results by two. If the pool's dimensions are in feet, the volume will be in cubic feet. One cubic foot of water equals 7.5 gallons.
Example: The water volume of a pool 60 ft. long, 30 ft. wide and that slopes in depth from 3 ft. to 10 ft. is as follows: 30 x 60 x ((10 + 3)/2) = 11,700 cubic ft. of water 11,700 x 7.5 = 87,750 gallons
It depends on how deep you fill the pool. So, let's take the most common depths for a 33-foot round pool; 3, 4 and 5 feet: For 3 feet of water the total gallons will be about 19,275. For 4 feet of water the total gallons will be about 25,700. For 5 feet of water the total gallons will be about 32,125.
That depends on how DEEP the pool is. The information provided only permits calculation of the AREA of the pool, not the volume and gallons are units of volume not area. To give you some idea though - here are the gallons for different depths: To fill the pool to a depth of 2 ft would require 1436 gallons To fill the pool to a depth of 3 ft would require 2154 gallons To fill…
