Question

5. Using Euler's formula, find the unknown. Polyhedron Il 1 ( 10 8 Faces 6 12 Vertices 9 (iii) 12 Edges​

Answer 1

Answer:

Euler’s formula: F + V - E = 2

Where , F = Faces, V = Vertices and E = Edges

i) F + 6 - 12 = 2

F = 2 + 6

F = 8

ii) 5 + V - 9 = 2

V-4 = 2

V = 6

iii) 20 + 12 - E = 2

32 - E = 2

E = 30

hope it's helpful to you

Answer 2

Euler's Formula:F+V-E=2

where,F=faces,V=vertices and E=edges

1) F+6-12=2

F=2+6

F=8

2) 5+v-9=2

v-4=2

v=6

3) 20+12-E=2

32-E=2

E=30
