- What is a cuboid;
- How to use our cuboid calculator;
- The surface area and volume of a cuboid formula; and
- How to manually calculate the surface area and volume of a cuboid.

## What is a cuboid?

**A cuboid** is a three-dimensional shape that has **six rectangular faces.** A cuboid's length, width, and height are of different measurements. The corners of these faces form right angles. Cuboids have **eight vertices and twelve edges.**

## How to use our cuboid calculator

Our *cuboid calculator* calculates the surface area of a cuboid as well as the volume. To calculate either of these two unknowns, you simply need to enter the length (`l`

), width (`w`

), and height (`h`

) of the shape, and the result will be generated in real-time.

As a bonus, you will also be able to see the diagonal of the shape.

## How to calculate the volume of a cuboid

To calculate the **volume of a cuboid**, we use the following formula:

So if we have the following problem:

**Find the volume of a cuboid whose length is 12 cm, width is 9 cm, and height is 10 cm.**

Using the above formula, we can then say:

## How to calculate the surface area of a cuboid

We calculate the surface area of a cuboid by finding the sum of the area of its six faces. To calculate the surface area of a cuboid (`SAC`

), we use the following formula:

So if we need to find the total surface area of a cuboid whose length is `8 cm`

, width is `7 cm`

, and height is `6 cm`

, using the above, we begin by substituting the values:

## FAQ

### What is the difference between a cube and a cuboid?

The main **difference between a cube and a cuboid** is that the length, width, and height of a cube are of equal measurements. On the other hand, a cuboid has length, width, and height that are of different sizes.

### How do I calculate the volume of a cuboid?

To calculate the **volume of a cuboid** you need to:

- Get the length, width, and height.
- Put the dimensions into the formula:

`volume = (l × w × h)`

cubic unit. - Do the calculation to find the answer.
