A trough is 6 meters long, 2.5 meters wide, and 3 meters deep. The vertical cross-section of the trough parallel to an end is shaped like an isoceles triangle (with height 3 meters, and k base, on top, of length 2.5 meters). The trough is full of water (density 10005: ). Find the m amount of work in joules required to empty the trough by pumping the water over the top. m (Note: Use 9 = 9.82 as the acceleration due to gravity.) .9 Joules
