A tank is in the shape of a prism with sides that are isosceles triangles with a base of 6 feet (at the top of the triangles) and height 4 feet.  The length of the tank is 20 feet, and water weighs 62.5 pounds per cubic foot. a.  Set up an integral representing the work required to fill the tank if water is pumped in from the bottom.  Use your calculator to evaluate it. b.  Set up an integral representing the hydrostatic force on one of the triangular sides of the tank when it is completely full.  Use your calculator to evaluate it.
