Midterm 2, Physics 6C, Fall 2014 David Schriver Name Problem A solid cube with side length 0.415 m and mass density po floats at submerged in salt water (mass density: 1025 kgm) with i above the surface as shown in the figure. ts top a distance d = 0.324 m [5 pts a) What is mass density po of the cube? [5 pts] b) What is the total pressure acting on the bottom surface of the cube under water? [5 pts] c) What is the total pressure acting on the top surface of the cube above the water? [10/pts] d) If a mass m is now placed on top of the cube, what is the smallest value of m such that the cube will be fully submerged under water?
