A cylinder of specific gravity 0.95 and length 0.8 m floats with its axis vertical in a vessel containing water and oil of specific gravity 0.84. What is the minimum depth of oil required to ensure that the cylinder will be totally immersed?

A cube of steel 0.25 m on each side floats in mercury. The specific gravities of steel and mercury are 7.6 and 13.6, respectively. Determine the submerged depth of the cube.
