If the mesh is strictly 3d, you can use

. Tools/Plugins:
- New view
- MathEval (Expression0 = 1)
- Integrate

but if there are also lower dimensional elements, their measures will
also be added to the answer...  See

for a discussion.  (Add do let me know if you come up with a better
answer as I'm still looking myself.)
