A pyramid is a structure usually with a quadilateral base whose outer surfaces are triangular and converge to a single point at the top known as the apex.

The volume of a pyramid depends on the shape of its base. For this case, we will use a square based pyramid.

**Formula to calculate volume of a pyramid.**

**Example:**

Calculate the volume of the following pyramid.

Therefore, the volume of the pyramid is 15 cmÂ³ .
