Question

the number of face of a pyramid is 5. find the number of its vertices when it's edges are eight

Answer 1

Answer:

Step-by-step explanation: f+v=e+2

5+v= 8+2

5+v= 10

V= 10-5

V=5

Answer 2

Given:

Number of faces=5

Number of edges=8

To find:

The number of vertices

Solution:

The required number of vertices is 5.

We can obtain the vertices' number by using the following formula-

Edges+2=Faces+Vertices

So, the given pyramid's vertices can be obtained by using the given values.

On putting the values,

8+2=5+vertices

10-5=vertices

5=Vertices

So, the pyramid has 5 vertices.

Therefore, the required number of vertices is 5.
