A trapezoidal tank with dimensions in meters as shown in the graph below is filled with water up to a
level of 3 meters. Choose the integral that calculates the work (in J) done to empty the tank by
pumping all the water to the top of the tank. Here, p = 1,000 is the density of water and g is the
gravitational acceleration constant.
