A tank in the shape of a triangular prism is full of water. Find the work W required to pump the water out of the spout. (Use 9.8 m/s2 for g. Use 1000 kg/m3 as the weight density of water. Assume that a = 4 m,b = 4 m,c = 12 m, and d = 1 m.) You may have to use similar triangles to solve this problem so keep that in mind...
