Today, we will be learning about ** pyramids**. Pyramids exist all around us, from man-made architectures to everyday objects that we are used to seeing. So, without further ado, let’s begin!

__What are pyramids?__

__What are pyramids?__

Based on geometrical terms, a pyramid is a polyhedron (a three-dimensional shape with flat ** polygonal faces**, straight edges and sharp corners or vertices) formed by connecting a

**and a point called the**

__polygonal base__**or**

__apex__**.**

__vertex__Note: A polygon is essentially a plane figure that is made up of a finite number of straight-line segments (at least three and above) connected to form a closed polygonal chain.

The number of straight-line segments is typically ** five or more**, because we know that a three-sided polygon is called a triangle, and four-sided polygon is either called a rectangle or a square.

The general formula to find the volume of a pyramid is:

**V = 1/3 l w h OR V = 1/3 X Base Area X Height**
