We can use the formula for the volume of a rectangular prism, which is:
Volume = length x width x depth
Plugging in the given values, we get:
7200 = length x 20 x 9
Dividing both sides by 180 (or multiplying by 1/180), we get:
length = 7200 รท (20 x 9) = 40
Therefore, the length of the pool is 40 feet.
