pool volume is 15 x30x4 = 1800 cu ft
there are 7.48 gallons in one cu ft
7.48*1800 = 13,464 gallons
depth of pool is 12 x 4 = 48 inches
13464/48 = 280.5 gallons per inch
7,480.52 gallons for every inch of depth
478.75 gallons for each inch of water depth.
44.883 gallons for each inch of depth. (rounded) 538.6 gallons for each foot of depth. (rounded)
22.44 gallons for each inch of the water's depth.
19" x 42" x 6" = 4,788 cubic inches = 20.727 gallons (rounded)
2000 Gallons
To determine how many gallons of water can fit in a square inch, you need to consider the depth of the water. A square inch is a measure of area, and without a specified depth, it cannot hold a volume of water. However, if you have a specific depth (e.g., 1 inch), you can calculate the volume in cubic inches and then convert that to gallons (1 gallon = 231 cubic inches). For example, 1 square inch of water at a depth of 1 inch would hold approximately 0.004329 gallons.
