A trough is 2 meters long, 2 meters wide, and 4 meters deep. The vertical cross-section of the trough parallel to an end is shaped like an isoceles triangle (with height 4 meters, and base, on top, of length 2 kg meters). The trough is full of water (density 1000- ). Find the amount of work in joules required to m³ m empty the trough by pumping the water over the top. (Note: Use g = 9.8- as the acceleration due to 8² gravity.) Joules
