en.wikipedia.org/wiki/Pyramid_(geometry)

In geometry, a pyramid is a **polyhedron** formed by connecting a polygonal **base**
and a point, called the apex. Each **base** edge and apex form a triangle, called a
lateral face. It is a conic solid with polygonal **base**. A pyramid with an n-sided
**base has** n + 1 vertices, n + 1 faces, and 2n edges. All pyramids are self-dual. A

Does a **polyhedron have only one base**? Yes, a **polyhedron** is **only** made up of
**one base** which is bordered by straight lines. Each face is in fact a polygon, a
closed shape in the flat 2-dimensional plane made up o…f points joined by
straight lines. Traya123 ...

In this unit we'll study three types of space figures that are not **polyhedrons**.
These figures **have** curved surfaces, not flat faces. A cylinder is similar to a prism,
but its two **bases** are circles, not polygons. Also, the sides of a cylinder are curved
, not flat. A **cone has one** circular **base** and a vertex that is not on the **base**.

These figures have some things in common with polyhedra, but they all have
some curved surfaces, while the surfaces of a **polyhedron** are always flat. First,
the cylinder. The cylinder is ... They **both have just one base** and they converge to
a point, the vertex. The formula for the volume of a **cone** is: Since the **base** area is

Thus a cylinder is not a **polyhedron** for several reasons: its lateral surface is not
plane, its **bases** are not polygons, finally it **has** no vertex! ... the vocabulary used
to describe polyhedra, but also use this vocabulary for describing other solids (so
the **cone** is supposed to **have** two "faces" and **one** "edge", the ball **just one** "face".

Examples of Polyhedra: Cube Its faces are all squares. Triangular Prism Its faces
are triangles and rectangles. Dodecahedron What faces does it **have**? So no
curved surfaces: **cones**, spheres and cylinders are not **polyhedrons**.
