Problem

A solid rectangular block has mass

240\,\text{g}

and its dimensions are

5\,\text{cm}\times 3\,\text{cm}\times 2\,\text{cm}

. (i) Calculate the density of the block in

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

. (Take the volume of the block to be the product of its dimensions.) (ii) Express the density obtained in part (i) in

\text{kg\,m}^{-3}

. (Use

1\,\text{cm}^{3}=1\times 10^{-6}\,\text{m}^{3}

.) (iii) Water has a density of

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

. Will the block float or sink in water? Give a reason for your answer.
