Question 4. Can a polyhedron have 15 faces, 30 edges and 20 vertices?

Answer:

Can a polyhedron have 15 faces, 30 edges and 20 vertices.
∵ F + V = E + 2
⇒ 15 + 20 = 35 and 30 + 2 = 32
∵ 35 ≠ 32
∴ It has not.

Question 5. If a polyhedron has 8 faces and 8 vertices, find the number of edges.

Answer:

A polyhedron has 8 faces and 8 vertices.
∴ Number of edges = F + V – 2 = 8 + 8 – 2 = 14

Question 6. If a polyhedron has 7 faces and 10 vertices, find the number of edges.

Answer:

A polyhedron has 7 faces and 10 vertices.
∴ Number of edges = F + V – 2 = 7 + 10 – 2 = 15

Question 7. Write the number of faces, vertices and edges in

(i) an octagonal prism
(ii) decagonal pyramid.

Answer:

Question 7. Write the number of faces, vertices and edges in
