well I am going to assume this child's wading pool is a cylinder because that is all that comes to mind at the moment. If this is true, the formula is V=pi(r)^2h
pi as in 3.14...... 
the diameter is 5 feet so to find the radius divide it by 2 therefore r=2.5
V=pi(2.5)^2(1)
V=19.63 (about) cubic feet 
then multiple this by 7.5 for gallons
