Global Interference will show any overlapping volumes in an assembly

Mass Properties will give you the volume/weight of a component or assembly.

The figure for volume is likely to be shown as an exponential figure in the modelling units.

In the example above VOLUME 8.5010447e+03 MM^3 , move the decimal place plus 3 places to give 8501.0447 MM^3.   Remember to convert this figure if you need different units:

1000mm^3 = 1cm^3      8501.0447mm^3  =  8.5cm^3  [approx]
