Jan,

Unfortunately, it looks like the Mathematica ConvexHull function is 
limited to 2D problems. You can, however, download "qhull" for free at:

http://www.geom.uiuc.edu/software/download/qhull.html

Qhull can handle convex hull problems with three (or more) dimensions, 
and can calculate volume.
