A man is standing on a raft, which is a large block of wood with dimensions 1.35 m by 1.35 m by 0.275 m. The raft is floating in water, with 85.0% of its volume submerged below the surface of the water. The density of the wood is 0.665 g/cm3, and the density of water is 1.00 g/cm3. (a) Calculate the magnitude of the buoyant force that the water exerts on the raft. Give your answer in units of Newtons (N). (b) What is the mass of the man? Give your answer in units of kilograms (kg).
