fluids: A body of density D is dropped from rest from a height h into a lake of density d (d>D). Neglecting all dissipativ forces, the maxm depth to which the body sinks before returning to float on surface is:? (ans: hD/d-D)

D is density of the body h - height from which the body was dropped d - density of a lake to which the body was dropped All these values are given
I don't get the formula, What is "D" and "h" and "d" ?
