Do all solid shapes have 6 faces?
You usually get the part of the word that means the particular number and put it before hedron (for solid shapes). E.g. Because a pentagon has 5 sides and a hexagon has 6 sides, "penta" means 5 and hexa means 6. Going by this rule, you can have hexahedrons, heptahedrons, octahedrons, nonahedrons, decahedrons, etc. for 6, 7, 8, 9 and 10 faced solid shapes respectively.
