A cube having a density of 3,672 kg/m3 is submerged in a fluid having a density of 8,463 kg/m3. Each side of the cube is 2.35 m in length. An external force is applied to the cube so that it is held at rest at a depth of 2,500 m (the bottom of the cube is at this depth). a. Calculate the weight of the cube. b. Calculate the buoyant force acting on the cube c. Calculate the absolute pressure acting on the top of the cube. d. If the cube is released, will it sink or float?
