Ugh. Ok so I have been working on this problem for 3 days and haven't gotten anywhere wiht it. Ok so you have a triangular vat. the height of each triangle on the ends is 3 m and the base of each triangle is 4 m. The length of the vat is 6 m. The water inside the vat is 2 m high. Now I need to find out the work needed in order to push the 2m's of water out. I come up wiht all these different set ups of integrals but htey don't work out in the end. Can someone come up with one?
