Q60 of 176 Page 125

A piece of steel has a volume of 12 cm3, and a mass of 96 g. What is its density: (i) In g/cm3? (ii) In kg/m3?

Volume, V= 12cm3= 12 × 10-6

Mass, m = 96 g = 96 × 10-3


We know,


Density, D = m/ V


(i) In g/cm3


D = 96/12


= 8 g/cm3


ii) In kg/m3


D = 96 * 10-3 / 12 * 10-6


= 8 * 103 kg/m3
