A hexagon is a plane (2-dimensional) figure whereas a hexahedron is a solid (3-dimensional) shape. A hexagon is bounded by six straight lines whereas a hexahedron is bounded by six polygons.
http://en.wikipedia.org/wiki/Hexahedron Generally, a hexahedron is any polyhedron with six faces, most commonly a cube. No hexahedron has a hexagon for any of its faces; most have squares or triangles.
yes
No. They may be of different sizes.

No. Not even all hexahedrons are cubes.
Soccer balls have different patterns, but if you have both regular pentagons and regular hexagons it must have 12 pentagons and 20 hexagons.
Infinitely many
20 hexagons
No. All hexagons are polygons.
Cube
On an official soccer ball you will find 20 hexagons and 12 pentagons. There are 60 points in which the corners of the hexagons and the hexagons connect, and the hexagons and the pentagons connect. The 20 hexagons are white, while the 12 pentagons are white.
4 hexagons; A hexagon has 6 sides, thus, if you have 4 hexagons, 4x6=24
