Question

calculate the mass of body in tones whose volume is 4m3 and R.D.is 5.2.

Answer 1

Volume of the body V = 2 m3Relative density of the body = Density of the body/Density of water Density of the body = R.D. x Density of water                                  = 0.5 x 1000 kg/m3 = 500 kg/m3 Therefore mass of the body = volume x density                                              = 2 m3 x 0.5 x 1000 kg/m3                                                                  = 1000 kg.
