  1. 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
