Question

If a polyhedron has 9 faces and 9 vertices. Find the number of edges in polyhedron and also draw the corresponding polyhedron. [3 MARKS]

Answer 1

Number of edges : 1 Mark
Figure : 2 Marks

By $Eule{r}^{\prime }sFormula$
we know that,

F + V – E = 2

9 + 9 – E = 2

E = 16

No. of edges = 16

Corresponding polyhedron
