A solid copper cube has an edge length of

10\,\text{cm}

at a temperature of

20\,^\circ\text{C}

. The coefficient of volume expansion of copper is

5.1\times10^{-5}\,\text{K}^{-1}

. Calculate the change in its dimensions when the temperature is raised uniformly to

120\,^\circ\text{C}

. (i) Find the increase in volume of the cube. (ii) Determine the new edge length of the cube, correct to

0.01\,\text{mm}
