Cube (Hexahedron)

Cube (Hexahedron) Facts

Notice these interesting things:

  • It has 6 Faces
  • Each face has 4 edges (and is a square)
  • It has 12 Edges
  • It has 8 Vertices (corner points)
  • and at each vertex 3 edges meet
  • It is one of the Platonic Solids


Volume and Surface Area

Volume = (Edge Length)3

Surface Area = 6 × (Edge Length)2

A cube is also called a hexahedron because it is a polyhedron that has 6 (hexa- means 6) faces.


Cubes make nice 6-sided dice, because they are regular in shape, and each face is the same size.

In fact, you can make fair dice out of all of the Platonic Solids.

Salt crystals grow in cube-like shapes.
(Because the atoms link up as corners of a cube.)
