A rectangular swimming pool is 10 meters wide and 21 meters long. The pool slopes uniformly along its length from a depth of 1 meter at the shallow end to a depth of 3 meters at the deep end. Assuming the pool is full, find the work required to pump the water out of the pool to a level 0.4 meters above the top of the pool. Make sure you show your work, and give your answer to the nearest Joule. Assume the density of water is 1000 kg/ms
