Total number of faces in a pyramid which has eight edges is______. Fill in the blank to make the statement true.

Solution:

Given, Total number of faces in a pyramid which has eight edges is______.

We have to fill in the blanks to make the statement true.

We know that the number of faces and vertices are the same in a pyramid.

So, F = V

Euler’s formula for any polyhedron is, F + V – E = 2

Where F stands for number of faces,

V for number of vertices

E for number of edges.

Given, E = 8

Now, F + F - 8 = 2

2F - 8 = 2

2F = 2 + 8

2F = 10

F = 10/2

F = 5

Therefore, the number of faces is 5.
