   Cross Section
   EXPLORE THIS TOPIC IN the MathWorld Classroom 

   A cross section of a solid is a plane figure obtained by the
   intersection of that solid with a plane. The cross section of an
   object therefore represents an infinitesimal "slice" of a solid, and
   may be different depending on the orientation of the slicing plane.
   While the cross section of a sphere is always a disk, the cross
   section of a cube may be a square, hexagon, or other shape.
