a pentahedron is a shape that has five sides and is formed by a pentagon

a penthedron is one of the hardest shapes to draw and it is scenitificly proven that it is has 26 sides not 25 —Preceding unsigned comment added by 211.30.192.50 (talk) 06:24, 11 September 2007 (UTC)

I beg to differ. According to MathWorld, the only regular polyhedron that can be formed by pentagons is a dodecahedron, which has 12 sides. The point is, a polygon with five regular flat sides is impossible, at least in our dimension or whatever. I emphasise "flat" because it's possible to have a sphere cut into 5 identical faces, but they're not flat. HУтaяtalk2mecontribs 18:10, 14 January 2009 (UTC)
