A flat ball? (Posted on 2004-04-08) Difficulty: 2 of 5
Soccer balls are usually covered with a design based on regular pentagons and hexagons.

How many pentagons/hexagons MUST there be, and why?

The surface of a soccer ball is a polyhedron consisting of 20 hexagons and 12 pentagons. They discussed this in the wonderful Indian football (soccer) movie "Bend It Like Beckham".
