A large tank is designed with ends in the shape of the region between the curves y=x22 and y=10 measured in feet. Find the hydrostatic force (in lb) on one end of the tank if it is filled to a depth of 8 ft with gasoline. Assume the gasoline's weight density is 420lbft3 (In British units, "weight density" is the equivalent of g in SI units.)
