Question

How many faces, edges and vertices does the shape below have?

Answer 1

PENTAGONAL PYRAMID

Answer:

Faces = 6

Edges = 10

Vertices = 6

Explanation:

A face is any of the flat surfaces of a solid object, meaning that the pentagonal pyramid has got 6 faces in total; 5 triangles, and 1 pentagon (5+1=6)

An edge is a line segment where two faces meet, and they also join each vertex with another. So if we look at the base of the pentagonal pyramid (which is a pentagon) we can see that it has got 5 edges, and then, when we look at the edges that connect the triangles with eachother, there are 5 more edges, so 5+5=10.

A vertex is where two or more line segments (edges) meet. The base (pentagon) has 5 vertices, and at the top, where the 5 triangles' edges connect, there is another vertex (just 1). So 5+1=6.

Answer 2

This is a pentagonal prism

- it has 6 faces
- 6 vertices
- 10 edges
