A rectangular Block of wood of square cross section of side Sand length L greater then S is to float in fresh water with its horizontal axis parallel to the waterline, the sides are vertical and in neutral equilibrium. Calculate the relative density of wood.

Now how am i supposed to approach this question and give a number when no numbers are given to me

Mass= VOL X Density

RD= Density of wood \ density of water

I have no mass, no definite vol, the only variable i have to work with is the 1000kg\m3 density of fresh water.

Ive been looking for similar problems in the Derrett Stability book with no success.

Any help would be greatly appreciated and i will most definatly have more questions as i go through the questions.
