The volume of a plastic covered sealed box is 350 cm³ and the box has a mass 500 g. Will the box float on water or sink in water? What will be the mass of water displaced by the box?

Answer»

The density of the substance is more than the density of water (1 G cm-3). Hence, it will sink in water.

As the PACKET is fully submerged in water,

MASS of water displaced by the packet = volume of the packet x density of water

                                                    = 350 CM3 × 1 g/cm3 = 350 g
