An aluminum sphere, radius = 10 cm, is to be hollowed out so that it will not sink in water. What is the minimum radius of the hollow? (density of Al = 2.70 g/cm3). I've tried to solve this problem several times, but my answers just have not been making sense. Please walk me through the thought process and way to conceptualize this problem.

IF YOU CANNOT SOLVE THEM ALL THEN PLEASE DONT SOLVE ANY.
A hollow aluminum sphere, with an electrical heater in the center, is used in tests to determine the thermal conductivity of insulating materials. The inner and outer radii of the sphere are 0.15 and 0.18 m, respectively, and testing is done under steady-state conditions with the inner surface of the aluminum maintained at 250°C. In a particular test, a spherical shell of insulation is cast on the outer surface...
