In this lesson, we will learn about the volume
of a cube.

About This Lesson

This lesson will explain the following things:
**study tips** and **math video**
below will explain more.

- How to derive the formula for the volume of a cube
- Using the formula to calculate the cube's volume
- Using the volume formula to calculate the length of each side (edge) of a cube

Tip #1

In the last lesson, we learned that the volume (**V**) of a rectangular solid
can be calculated by multiplying the
width (**W**), length (**L**) and height (**H**)
of the solid together. The formula is shown below:

Now, a cube is a special form of a rectangular solid because the sides (edges)
of the cube have the same length.
Therefore, if the length of a side of the cube is **L**, the width, length and
height will have the length **L**.

With this, we can derive the formula for the volume of a cube as shown below:

V =WLH

With this, we can derive the formula for the volume of a cube as shown below:

Hence, we have the formula:V =WLH

=L×L×L

=L^{3}

The math video below will explain more about this formula. Also, you will see some examples on using it...V =L^{3}
