Steps to Measure...
1st- Create a plane (till you want to measure volume)
2nd- Go on "Intersect"
3rd- In intersect take "Create internal regions" option.
4th- Select Plane and Part.
4th- Take "intersect" then OK

By above steps you will get a solidbody as a volume of internal area, now select mass properties and get volume of that internal part(new solidbody).
