# How many faces, edges, and vertices are in an octagonal prism?

An octagonal prism is a three-dimensional polyhedron bounded by 2 octagonal bases and 8 rectangular sides.

## Answer: An octagonal prism has 10 faces, 24 edges, and 16 vertices.

Let's draw an image of an octagoanal prism.

**Explanation:**

**Faces:**

8 vertical faces + top face + bottom face = 10 faces

**Edges:**

8 vertical edges + 8 top edges + 8 bottom edges = 24 edges

**Vertices:**

8 vertices where the top edges meet the vertical edges + 8 vertices where the bottom edges meet the vertical edges = 16 vertices

### Thus, an octagonal prism has 10 faces, 24 edges and 16 vertices.
