All of us have seen a pyramid – whatâ€™s its shape? Conical! Thatâ€™s right. What about football? What is the shape of a football? Spherical, youâ€™d say? Youâ€™re right again. So, whatâ€™re these shapes? These are solid shapes. In simple terms, weâ€™re visualizing solid shapes. So, in this chapter, you will learn more about visualizing solid shapes. NCERT Solutions for Class 8 CBSE Maths Chapter 10, presents different dimensions of shapes and geometrical figures to the students. It includes some very interesting concepts such as visualising solid shapes, views of 3d-shapes like cubes, cones, cylinders, spheres, etc. mapping space around us and faces, edges and vertices.

**Exercise 10.3 Page No: 166**

**1. Can a polyhedron have for its faces:**

**(i) 3 Triangles?**

**(ii) 4 triangles?**

**(iii) A square and four triangles?**

**Solution:**

(i) No, it is not possible to construct polyhedrons of such shape. A polyhedron should have minimum 4 faces.

(ii) Yes, a triangular pyramid will have 4 triangular faces.

(iii) Yes, a square pyramid has one square face and 4 triangular faces.

**2. Is it possible to have a polyhedron with any given number of faces? (Hint: Think of a pyramid)**

**Solution:**

It is possible, but only if the number of faces is 4 or more.

**3. Which are prisms among the following:**

**Solution:**

(i) A nail: It is not a polyhedron as it has a curved surface on an end; it is also not a prism.

(ii) This is an unsharpened Pencil; It is a prism.

(iii) This is a table Weight; it is not a prism.

(iv) This is a box; it is a prism.

**4. (i) How are prisms and cylinders alike?**

**(ii) How are pyramids and cones alike?**

**Solution:**

(i) A cylinder can be called a circular prism, a prism with a circular base.

(ii) A cone can be considered to be a circular pyramid, a pyramid with a circular base.

**5. Is a square prism same as a cube? Explain.**

**Solution:**

Yes, a square prism can also be considered to be a cube. A square prism has square shape at its base. However, its height imay not be the same as the side of the square. So, a square prism can also be a cuboid.

**6. Verify Eulerâ€™s formula for these solids.**

**Solution:**

(i) Number of faces, F = 7

Number of edges, E = 15

Number of vertices, V = 10

As per formula, F + V â€“ E = 2

Substitute the values, we have

F + V â€“ E = 7 + 10 â€“ 15

= 2

Hence, verified.

(ii) Here, F = 9, V = 9 and E = 16

Using formula, F+ V â€“ E = 2

F + V â€“ E = 9 + 9 â€“ 16 = 2

Hence, Eulerâ€™s formula is verified.

**7. Using Eulerâ€™s formula, find the unknown:**

Faces | ? | 5 | 20 |

Vertices | 6 | ? | 12 |

Edges | 12 | 9 | ? |

**Solution:**

Eulerâ€™s formula: F + V â€“ E = 2

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

(i) F + 6 â€“ 12 = 2

F = 2 + 6

â‡’ F = 8

(ii) 5 + V â€“ 9 = 2

V â€“ 4 = 2

â‡’ V = 6

(iii) 20 + 12 â€“ E = 2

32 â€“ E = 2

â‡’ E = 30

**8. Can a polyhedron have 10 faces, 20 edges and 15 vertices?**

**Solution:**

From the given data, we have

F = 10

E = 20

V = 15

Every polyhedron satisfies Eulerâ€™s formula, which is stated as, F + V â€“ E = 2

For the given polygon,

F + V â€“ E = 10 + 15 â€“ 20 = 25 â€“ 20 = 5, which is not equal to 2

Therefore, A polyhedron is not possible as Eulerâ€™s formula is not satisfied.
