Q52 of 176 Page 124

Calculate the density of an object of volume 3 m3 and mass 9 kg. State whether this object will float or sink in water. Give reason for your answer.

Volume = 3m3

Mass = 9kg


Density of substance =


= = 3kg/ m3


And density of water = 1000kg/ m3


The object will float in the water as the density of the object is less than the density of water.
