Detailed Solution

Concept- Try to remember how the pyramid was built, and concentrate on the design of the side faces. It's important to keep in mind that a pyramid's base and side faces have different shapes.
Let's begin the solution by understanding a pyramid's structural characteristics and creating a graphic that accurately depicts them. The term "pyramid" generally refers to the historic Egyptian structures created to house mummies. In mathematics, a polyhedron with triangles forming its side faces and a polygon serving as its foundation is referred to as a pyramid. The pyramid's apex is where the side faces come together. The lateral faces of a pyramid are often referred to as its side faces.
Now, for better visualization, let's create a diagram.
