## What is cube

A cube is a regular solid formed by six square faces, six right-angle triangles, and twelve edges.

A cube can also be said to be a cuboid or a rectangular box. The length, width, and height of a cube are equal to the length of its edges, which means that it is a perfectly symmetrical shape.

## Math formula

- Diagonal of cube = a√3 = side x √3
- Cube of volume = (side)³ = a³
- Curved/Lateral Surface Area of cube = 4a² = 4(side)²
- Total Surface Area of cube = 6a² = 6(side)²

## Solved example

Example: Cube side = 15 cm, find the volume of a cube, the diagonal of the cube and the total surface area

**Given values**, cube side = 15 centimeters

**Diagonal of cube = **a√3 = 25.981 cm

**Volume of cube = **a³ = 3375 cm³

**Curved surface area = **4a² = 900 cm²

**Total surface area = **6a² = 1350 cm²
