box3dVolume

BOX3DVOLUME Volume of a 3-dimensional box.

   V = box3dVolume(BOX)

   A box is represented as a set of limits in each direction:
   BOX = [XMIN XMAX YMIN YMAX ZMIN ZMAX].

   Example
   [n e f] = createCubeOctahedron;
   box = boundingBox3d(n);
   vol = box3dVolume(box)
   vol = 
       8
