The wood is #2/3# as dense as water.


The question is not clear but I think this is likely what you are looking for.

If #2/3# of the block of wood is submerged then
#color(white)("XXX")#the mass of water displaced by #2/3# of the volume of the block of wood is equal to the mass of the block of wood.

Another way to say this is:
each unit volume of wood can be supported by #2/3# of a unit volume of water.
