How many sides are on a die?

Answer 1

A die can have any number of sides; one-sided dice are a joke in the form of a sphere and two-sided dice are often a simple coin shape. Others use platonic solids to give the required number of sides.
The most commonly used are six-sided dice, noted as d6 and usually cubic, but other common numbers include d4 (a tetrahedron), d8 (an octahedron), d10 and d12 (a dodecahedron).
