Have a calculator handy? pi x r squared x depth x 7.5 = capacity in gallons. 18' pool has a 9' radius Radius squared is 9x9 or 81. Multiply 81 by pi (3.14)= 254.34. This is the square footage of the pools surface. Also good to know if you want to add a heater or some chemicals that require surface area numbers. The surface area times the depth gets you the cubic feet capacity of the pool, again sometimes good to know. So, 254 x 4' deep = 1,016 cubic feet. There are 7.5 gallons of water in a cubic foot. 1,016 x 7.5 = 7,620 gallons
Approximatly 7647 gallons of water, according to my pool records.
7200 gallons
We can't be sure - we need another dimension. If the Pool is 20 feet long by 48 feet wide, we need to know how deep it is - a 2 foot deep pool will not hold as much as a 10 foot deep pool. If the pool is not a uniform depth, there are formulae used to determin how much water the pool will hold. Try calling Anthony. Or Esther Williams.
A 1000 acre lake that is 7 feet deep (uniformly) will have 7000 acre feet of water in it. An acre foot is an acre of water one foot deep, and the unit is used to measure reservoir water capacity. The conversion factor is that one acre foot equals about 325,851.5 gallons. The lake in question is holding 7000 times 325,851.5 gallons of water.
half a pint
There are 13,536 gallons in a 24 foot diameter pool that has 4 feet of water. Not true for a pool that is 4 feet in height. This would hold less than 4 feet of water.
Filled to the top, this well would hold about 956 gallons of water.
This pool can hold up to 1,689.7 gallons of water.
Assuming that you're referring to a cylindrical pool that has a 30 foot diameter and is evenly 10 feet deep throughout, it should hold approximately 940 gallons of water.
enough
12 cubic feet
1350 cubic feet is the capicity of the pool which will hold 10,098 gallons of water
42" is 3½'.
Depends how deep it is. It is actually 3 ft deep. thus the question 12 foot by 3 foot. However, it will hold approximately 2,100 gallons or 10,000 litres of water
