One third height of a cubical block of edge 6cm is floating in kerosene oil of specific gravity 0.8. To make the block to be just immersed some water is poured. What is the height of the water column?

A cube of iron of edge 5 cm floats on the surface of mercury, contained in a tank. Water is then poured on top, so that the cube just gets immersed. Find the depth of water layer. (Specific gravities of iron-and mercury are 7.8 and 13.6 , respectively.)
