Problem

A rectangular metal block has mass

0.240\,\text{kg}

. Its length, breadth and height measured with a metre scale are

8.0\,\text{cm}

5.0\,\text{cm}

and

2.0\,\text{cm}

respectively. a. (i) Calculate the volume of the block in

\text{m}^3

. b. (ii) Determine its density in

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

. c. (iii) The density of water is

1000\,\text{kg}\,\text{m}^{-3}

. State, with reason, whether the block will float or sink when gently placed in water.
