A trough is 10 meters long, 3 meters wide, and 2 meters deep. The vertical cross-section of the trough parallel to an end is shaped like an isosceles triangle (with height 2 meters, and base, on top, of length 3 meters). The trough is full of water (density 1000 kg m 3 ). Find the amount of work in joules required to empty the trough by pumping the water over the top. (Note: Use g
