Question

a solid having 5 faces and and 9 edges find the number of vertices​

Answer 1

Answer:

Vertices = 6

Step-by-step explanation:

Using euler's formula

${Euler's formula = (Faces + vertices = Edges +2)}$

Number of faces = 5

Number of edges = 9

Number of vertices = V

According to euler's formula

5 + V = 9 + 2

5+V = 11

V = 11 - 5

V = 6

So the the solid has six vertices

Answer 2

Answer:

vertices = 6

Step-by-step explanation:

Edges = 9

Faces = 5

Use Euler's formula : V-E+F=2

V-9+5=2

V-4=2

V=2+4

V=6
