Question

A stone of mass 4.5 kg when dipped in a measuring cylinder containing water upto 60 ml its water level Rises up to 62.5 ML calculate the density of stone in gram centimetre cube and kilogram cubic metre

Answer 1

Mass = 4.5 kg

Change in density of the measuring cylinder = 62.5 ml - 60 ml = 2.5 ml

But, we know that

1 ml = 1 cubic cm

Therefore, 2.5 ml = 2.5 cm cube

=> Density = Mass / volume

=> Density = 4.5 / 2.5 = 1.8 kg cm cube
