When work is defined to be force times distance, and that the weight (force) of a liquid is equal to its volume times its density. A fish tank has a rectangular base of width 2 feet and length 6 feet and sides of height 5 feet. If the tank is filled with water weighing 62.5 lb per cubic foot, the work required to pump all the water just over the top of the tank is what?

When I spent about an hour on this (I know way too long) I got 9,375ft/lb, is this what I was supposed to get? Did I do something wrong?
