A rectangular tank with a base 3 feet by 4 feet and a height of 2 feet is full of oil. The oil weights 58.8 pounds per cubic foot. How much work is done in pumping water out of the top edge in order to empty the tank?

Answer came out to be 1410.

3X4 delta y 58.8(12)delta(y) distance (2-y) integrating at (0) and (2) => 705(2-y)dy = 1410 is this correct?
