Cube 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

A cube is also called a **hexahedron** because it is a polyhedron with 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 using all of the Platonic Solids.

Make your own Cube: cut out the shape and glue it together. |

Salt crystals grow in cube-like shapes.

(Because the atoms link up as corners of a cube.)

## Surface Area

**Surface Area** = 6 × (Edge Length)^{2}

### Example: Edge Length = 4

Surface Area= 6 × (Edge Length)

^{2} = 6 × 4

^{2} = 6 × 16

= 96

## Volume

**Volume** = (Edge Length)^{3}

### Example: Edge Length = 4

Volume= (Edge Length)

^{3} = 4

^{3} = 4 × 4 × 4

= 64
