**Question 3. Verify Euler’s formula for these solids:**

**Answer:**

**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 8. Using Euler’s formula, complete the following table:**
