This is because polystyrene has a density of 0.05 g/cm 3 which is much less than the density of water (1.0 g/cm 3) A wooden block will be partially submerged but will still float. This is because the density of a wooden block (0.9 g/cm 3) is slightly less than the density of water; An iron block will sink
