Problem

A hollow metallic cube is to be weighed for transport purposes. (i) The external edge of the cube is

12\,\text{cm}

and the metal is uniformly

0.6\,\text{cm}

thick. Calculate the volume of metal used to make the cube in

\text{cm}^{3}

. (ii) Convert the volume obtained in (i) to

\text{m}^{3}

. (iii) The density of the metal is

7.9\,\text{g cm}^{-3}

. Determine the mass of the hollow cube in kilograms.
