Enter the length of side to find the volume, surface area, and diagonal of a cube using cube calculator.

Cube calculator is an online geometrical tool that takes length of a side and calculates various parameters of a cube including:

- Surface area
- Volume
- Diagonal

## What is a cube?

A cube is a three-dimensional solid object bounded by six square faces with three meeting at each vertex. It has 8 vertices, 12 edges, and 6 faces. It is a trigonal trapezohedron in four orientations and regular square prism in three orientations.

### Volume of cube

Cube volume formula can be written as:

**V = a³**

### Surface area of cube

Surface area of cube formula can be expressed as:

**S = 6 × a²**

### Diagonal of cube

The formula for diagonal of cube can be stated as:

**D = √3×a**

Where,

*a* is length of side,

*V* is volume,

*S* is surface area, and

*D* is diagonal of cube.

Our cube volume calculator uses all of the above formulas to find these cube parameters.

## How to calculate volume of cube?

*Example:* If length of side of cube is *8 cm,* find the volume of cube.

**Cube calc: find V**

**Step 1: **Identify the given values.

*a = 8 cm*

**Step 2: **Place the value in volume of cube equation.

**V = a³**

**V = 8³ = 8 × 8 × 8 **

**V = 512 cm**^{3}

### How to calculate surface area of cube?

*Example:* If length of side of cube is *3.5 cm,* find the surface area of cube.

**Cube calc: find S**

**Step 1: **Identify the given values.

*a = 3.5 cm*

**Step 2: **Place the value in surface area of cube equation.

**S = 6 × a²**

**S = 6 × 3.5²**

**S = 73.5 cm**^{2}

### How to find diagonal of cube?

*Example:* If length of side of cube is *10 cm,* find the diagonal length of cube.

**Cube calc: find d**

**Step 1: **Identify the given values.

*a = 10 cm*

**Step 2: **Place the value in surface area of cube equation.

**D = √3×a**

**D = √3×10**

**D = 17.32 cm**
