• does not change

Answer explanation

In this example, temperature was raised from 353 K to 832 K and the length of the box (l) INCREASED from about 6 nm A to about 15 nm. The area (width x height) of the box is fixed, so if length increases by 2.5 times, volume would increase by 2.5 times as well.
