I've been working on this problem for the last hour and can't quite seem to get it right.
A tank is full of water. Find the work required to pump the water out of the spout. Use the fact that water weighs 62.5 lb/ft3. (Assume a = 4 ft, b = 5 ft, and c = 6 ft.)
I've figured out that the volume is 4*5*6/2= 60 and the mass= 60*62.5 = 3750 I then integrated 3750x from 0 to 4. 1875x^2]=30,000
Have I done this problem correctly?
