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.

## Cube formulas

### 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

**find the volume of cube.**

*8 cm,***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

**find the surface area of cube.**

*3.5 cm,***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

**find the diagonal length of cube.**

*10 cm,***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**
