Iceberg floats in sea water with a part of it submerged. The percentage fraction of the ice berg submerged is (Density of ice : 0.9 g cm-3, density of sea water : I . I g cm -3)

V be the volume of the iceberg, x be the volume out of sea water.The iceberg is floating in sea water thenVρiceg = (V-x)ρsea watergor V × 0.9×g = (V-x)1.1 g0.2 V = 1.1x∴xV = 0.21.1Percentage of fraction of the volume of iceberg above the level of sea water xV×100 = 0.21.1×100 = 18%
