Question

A pyramid on an $n$ sided polygon has ______ faces.

Answer 1

Definition of pyramid :

A pyramid has a polygonal base and flat triangular faces, which join at a common point called the apex. A pyramid is formed by connecting the bases to an apex. Each edge of the base is connected to the apex, and forms the triangular face, called the lateral face.

If a pyramid has an $n$-sided base, then it has $n+1$ faces, $n+1$vertices, and $2n$edges.

Hence, A pyramid on an $n$-sided polygon has $n+1$faces.
