Octagonal Pyramid: A Solid with 9 Faces
An octagonal pyramid is a three-dimensional geometric shape characterized by an octagonal base and eight triangular faces that converge at a single point called the apex or vertex. The total number of faces is calculated by adding the octagonal base and the eight triangular faces.
Properties of an Octagonal Pyramid:
- Faces: It has 9 faces (1 octagon and 8 triangles).
- Edges: It has 16 edges (8 from the octagon and 8 connecting the base to the apex).
- Vertices: It has 9 vertices (8 from the octagon and 1 apex).
| Feature | Description |
|---|---|
| Base | Octagon |
| Lateral Faces | 8 Triangles |
| Total Faces | 9 |
| Total Edges | 16 |
| Total Vertices | 9 |
Therefore, based on the reference provided, the octagonal pyramid precisely fits the description of a solid with nine faces.
