## Formula to calculate the volume of a cube

**The cube is a regular geometric figure.** which is composed of six faces whose shape is that of a square. This implies that all edges measure exactly the same.

This makes the calculations much easier, because if you want to calculate the area of a square we have to square the length of a side, to know the volume we have to **cubing the edge value**This is represented in the following mathematical formula:

cube volume = a^{3}

Let's imagine that we have a cube whose side measures 3 centimeters, in this case, the **volume of the figure** will be:

volume = 3 x 3 x 3 x 3 = 27 cm^{3}

It is important to remember that since we are working with volumes, **the unit also rises** cubed. In the previous example we start with centimeters and end with cubic centimeters.

If you want to calculate the volume of a rectangular cube, then we recommend that you learn how to calculate the volume of a rectangular cube. volume of a prismis practically the same but taking into account the different measurements of each side.

## How to calculate the area of a cube without knowing how long the edge is

It may be that in the mathematics exercise for **calculate the volume of a cube**do not give us how long the edge is, but give us how much is the surface of one of its faces.

In this case, we know that the surface of a square is equal to the base squared (b^{2}). Therefore, if **we know the surface area, we can find out how long one of the sides is** of the figure and from there, find its volume.

To do this, the first thing we have to do is to calculate how long the side of the face of the cube measures from its surface. Simply **we make the square root of the value of the surface area** and the result will be the length of the edge.

Finally, we cube the value obtained as we have seen in the previous point and that's it. We have found the volume of this regular figure from the surface of one of its faces.
