The answer will depend on whether the depth is in feet or inches or some other units.


How many gallons of water in a 18x48 pool?

The answer to this question will require some simple dimensional analysis and geometry. Assuming that he pool is a round above ground pool, 18 feet in diameter and 48 inches deep you first need to calculate the area of the swimming pool in square inches and then multiply by the depth in inches to get the volume in cubic inches: The pool is an 18 foot diameter circle. The diameter in inches of the 18 foot pool is 216 inches (18 feet x 12 inches / foot) The area of a circle = pi (3.1415) x radius x radius The radius = 1/2 of the diameter The area of an 18 foot diameter pool in square inches is: 3.1415 * 108 inches * 108 inches = 36643.5 square inches The volume in cubic inches of an 18 foot diameter pool is: 36643.5 square inches x 48 inches = 1758890 cubic inches. There are 231 cubic inches in one gallon so the volume of an 18 foot diameter, 48 inch deep pool is: 1758890 / 231 = 7,614 gallons If it is a square or rectangular pool simply multiply the length x the width x the average depth.


How many gallons of water are in a pool 72 inches by 15 inches?

Cannot be answered with only these measurements. You need to specify what shape the pool is. Also, for a rectangular pool, the length, width and depth are needed. For a round pool, the diameter and depth are needed.


Formula for gallons in a round pool?

Depth x Diameter-squared x 5.9 = Volume in Gallons


How many gallons of water in a 24 inch diameter x 48 inch long cylinder?

231 cubic inches = 1 gallon. To find out how many gallons will fill the tank, you must multiply the area of the tank by the depth to find the volume and then divide by 231 to figure how many gallons will fill it: volume of 41 inch dia by 93 inch depth = 122,783.93 cubic inches divided by 231 = 531.532 gallons. PS: I assumed the 41 inches diameter is the inside diameter. If it is the outside diameter, the thickeness of the walls need to be subtracted in order to find the inside diameter for a better calculation. The formula for Area is R (radius = half of diameter) squared X Pi (3.1416).


What is the gallon per inch of depth in a 64 inch diameter cylinder?

How many gallons does a six foot by fifteen inch round pool hold?

Cannot be answered with only these measurements. You need to specify what shape the pool is. Also, for a rectangular pool, the length, width and depth are needed. For a round pool, the diameter and depth are needed.


How do you calculate how many gallons of gasoline a tank would hold?

Length in inches x Hight in inches x Depth in inches = ???? cubic inches. 231 cubic inches = 1 gallon US. So ???? cubic inches divided by 231 will give you ?? gals USA:There are 7.48 gallons per cubic foot. Tank volume = diameter in feet x diameter in feet x .7845 x length in feet = cubic feet. Now multiply this by 7.48


How many gallons of water are in a 10ft diameter x3ft pool?

A round pool with a 10-foot diameter and a 3-foot depth can hold up to 1,762 gallons of water.


How many gallons of water is needed to fill a pool 15' diameter by 42 deep?

Is 42 in inches or feet? I've answered the problem below for inches since that makes more sense for a pool. Volume of pool = area of pool * depth V = pi*r^2 * depth = 3.14*7.5*7.5*3.5 = 618 cubic feet The volume of 1 gallon of water = 0.133680556 cubic feet. Therefore, the # of gallons of water in the pool = 618/0.133680556 = 4623 gallons of water In actually, because of significant digits in the depth and diameter of pool, the answer would be approximately 4600 gallons of water
