If its an oval pool approx 7800 gallons at full capacity. If its rectangular pool then approx 9000 Gallons.
Actually, since your pool is a rectangle, it will have a perimeter instead of a circumference. That is the distance around the outside. To get that, add all sides together. 15+15+24+24= the perimeter.
All three dimensions are required for volume
It depends on the units for 15, 24 and 4: inches, feet, metres, miles?
15 x 24 = 360 square feet. How deep is the pool? You need that to determine cubic feet of that area.
15000 gallons
Because putting a cover on your pool makes it much more hot in the space between the cover and the water. The water will evaporate much quicker because of the increased temperature.
Assuming that 24' is the diameter of the pool, then the volume of the pool is 3,387,491.39 cubic inches. There are 231 cubic inches in a gallon, so the pool holds 14,664.46 gallons of water.
