**How many edges and faces are there in pentagonal prism?**

In geometry, the pentagonal prism is a prism with a pentagonal base. It is a type of heptahedron with 7 faces, 15 edges, and 10 vertices.

### How do you find the edges of a pentagonal pyramid?

How do I find the base edge of a pentagonal pyramid given the height and slant height? I just need formulas.

- (height)2 + (apothem)2 = (slant height)2
- tan(54°) = apothem/(half the edge length)
- half the edge length = (apothem)/(tan(54°))
- edge length = (2×apothem)/(tan(54°))

**How many faces are there in pentagonal pyramid?**

## How many faces do a pentagonal pyramid have?

5 faces

The faces which can be seen from the side are triangles in shape and they meet at a point called apex which is the top of the pyramid. As we have to find the faces of a pentagonal pyramid, we know that it must have 5 faces that can be seen from the side. These 5 triangular faces on each side of the base.
