Consider a bar of aluminum which is 10 cm X ½ m X 20 m. If the bar undergoes a change in its temperature from 10° C to 20° C, determine the new dimensions of the bar.

2. Relevant equations

ΔL=αL_{0}ΔT

α=24x10^{-6}

3. The attempt at a solution

I understand how the formula works and everything. But my real question is as follows: does thermal expansion occur in all dimensions? Would each dimension increase?
