We cannot run the example you posted and formatting was missing. Please read [Read before posting: How do I get my question answered?](https://fenicsproject.discourse.group/t/read-before-posting-how-do-i-get-my-question-answered/21)

That being said, for the second integral you may want to have a look at `ufl.CellVolume`.
