A swimming pool is in the shape of a rectangular parallelepiped 8 ft deep, 38 ft long, and 24 ft wide. It is lled with water to a depth of 7 ft. How much work is required to pump all the water over the top? The weight of water per cubic foot is pg = 62.43 lb/ft3. (Round your answer to the nearest whole number.) A cylindrical tank, 6 m in diameter and 4 m high, is full of water. The tank is standing upright on a at circular end. How much work is required to pump half the water over the top of the tank? (The density of water is 1000 kg/m3). (Use symbolic notation and fractions where needed.)
