An aquarium 7 m long, 1 m wide, and 1 m deep is full of water. Find the work needed to pump half of the water out of the aquarium. (Use 9.8 m/s² for g and the fact that the density of water is
1000 kg/m³.)
Show how to approximate the required work by a Riemann sum. (Let x be the height in meters below the top of the tank. Enter x* as x₁.)
