[6 points ] 8. The fuel tank on a large truck has trapezoidal cross sections with dimensions (in feet) shown in the figure below. Assume that the engine is approximately 2 feet above the top of the fuel tank and that diesel fuel weighs approximately 55.6 pounds per cubic foot. Find the work done by the fuel pump in raising a full tank of fuel to the level of the engine. Hint: Use the fact that Work = AForce x Distance 4 3-11-2-+1 N 2 3 X
