21. We introduce the notion of density: ρ = m V and convert to SI units: 1 g = 1 × 10 3 kg. (a) For volume conversion, we find 1 cm 3 = (1 × 10 2 m) 3 = 1 × 10 6 m 3 . Thus, the density in kg/m 3 is 33 3 36 3 1 g 10 kg cm 1g cm 1 10 kg m . cm g 10 m §· § · == × ¨¸ ¨ ¸ ©¹ © ¹ Thus, the mass of a cubic meter of water is 1000 kg.
