Your swimming pool is square and 6.1 m on a side. It is 1.4 m deep in the morning. If the temperature changes by 19°C during the afternoon, how much does the depth of the water increase?

Use the same method I used here:

Only the pool dimensions have changed.

You need to assume a mean (average) temperature and use a mean thermal expansion coefficient for water, because it changes rapidly with temperature.
