A cube with side length L, and density ρC sits at rest on a bathroom scale at the bottom of a large tank. The tank is partially filled with a fluid having density ρf, leaving the cube partially submerged. A side profile view of the cube shows the cube face a distance d outside of the fluid, and a distance L-d submerged under the fluid. Determine the distance dwhen ρf= 2000 kg/m3, ρC= 4000 kg/m3and L = .50 m. Write...
