Question

Q.12 Can a polyhedron have 12 faces, 8 vertices an 18 edges?​

Answer 1

The two apexes and six points of the hexagon make eight vertices, there are twelve triangular faces (six meeting at each apex), and of course 18 edges. There is another way to make the solid nonconvex, as one cone could be "everted" inside the other.☺

Answer 2

Answer:-

$\:$

Yes

explanation:

We'll use Euler's Formula I.e. F+ V -E =2

L.H.S

=6+8-12

= 14-12

= 2

= R.H.S

As, L.H.S= R.H.S

A polyhedron can have 8 vertices, 12 edges and 6 faces.
