# How many gallons are in a 4 foot by 12 foot by 18 foot round swimming pool?

# How many gallons of water are in a 24 foot round pool that is 4 feet deep?

For a round above ground pool, the calculation is: Diameter x Diameter x Depth X 5.9 = Number of Gallons Please note that the depth is the ACTUAL water depth NOT the height of the pool wall (the water is usually around 6 inchs lower than the wall height). For your example: For a 24-foot round pool w…ith a actual water depth of 3.5 ft: 24x24x3.5x5.9 = 11,894 or around 12,000 gallons. (MORE)

# How many gallons of water does it take to fill a 24-foot by 4-foot swimming pool?

The basic formula to figure water volume or gallons of water for a specific size say 20 x 40 are as follows 20 x 40 = 800 x average depth(say 5') = 4000 x 7.5(gallons per cubic foot) = 30,000 In answer to your question you did not give enough information. Is it 24ft diameter? If so the formula is ra…dius squared x 3.14 x 4(average depth) x 7.5 Or 12 squared(144) x 3.14(452.16) x 4(a.d.)1808.64 x 7.5 = 13,564.8 gallons (MORE)

# How many gallons are in an 18-foot vinyl pool?

Answer 30536.28 gallons.
By figuring your pool's depth, you can then determine how much water your pool holds. This is how you would find the average depth: shallow end depth + deep end depth divided by 2..
Rectangular pool: Lenght x Width x average depth x 7.5 total gallons. Oval pool: full width… x full length x average depths x 5.9 total gallons. Sloping sides: If your pool has sloping sides, multiply the final figure by .85..

# How many gallons of water are in a 12 foot round by 3 foot deep pool?

This question illustrates why the standard units of measure are silly. This problem would be much easier if you had metric measures. It would be so much easier that I am tempted to convert to metric units, solve the problem, then convert back. However, I assume that you wanted to see the calculat…ions done in the units you gave so here is my answer. Assumptions: by 12 foot round, I assume you mean that the diameter is 12 feet. Volume = area of base * height Volume = Pi * radius * radius * height Volume = 3.14 * 6 * 6 * 3 ft 3 Volume = 339 ft 3 Now you need to know how many cubic feet are in a gallon. I don't know this and probably nobody else in the state of AK knows this, but you can look it up. 1 gallon = 0.1337 ft3 Number of gallons = Number of cubic feet / number of cubic feet per gallon Number of gallons = 2,536 gallons.
