A trough is 3 meters long 2.5 meters wide, and 5 meters deep. The vertical cross-section ofthe trough parallel to an end is shaped like an isoceles triangle {with height 5 meters. and base. on too. I: of length 2.5 meters]. The trough is full of water {densityf IDDD _g3 }. Find the amount of work in Ill joules required to ernotythe trough of; pumping the water over the too. [Note: Use g = 9.8 E; as E the acceleration d ue to gravity.)
