It all depends on the depth of the pool and if it changes because of a slope. The calculation you would want to use to calculate the gallons is convert the length and with to feet. Find the surface area, and then multiply that times the average/constant depth times 7.5(this is a constant variable for all pools).
Surface Area=Length x width
Volume=length x width x depth x 7.5
