assume you mean what fraction of the VOLUME is under water
density = 570 kg/m^3 where water is 1000 kg/m^3
UNITS MATTER !!!
mass of wood = 570 * volume = 200
mass of water displaced = 1000 * volume under water
so
1000 * volume under water = 200 = 570 * volume
so
volume under water/volume = 0.570
density = 570 kg/m^3 where water is 1000 kg/m^3
