All of us have seen a pyramid – what’s its shape? Conical! That’s right. What about football? What is the shape of a football? Spherical, you’d say? You’re right again. So, what’re these shapes? These are solid shapes. In simple terms, we’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. NCERT Solutions Class 8 Chapter 10 Visualising Solid Shapes chapter is very interesting and easy to understand

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 Euler’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 – E = 2

Substitute the values, we have

F + V – E = 7 + 10 – 15

= 2

Hence, verified.

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

Using formula, F+ V – E = 2

F + V – E = 9 + 9 – 16 = 2

Hence, Euler’s formula is verified.

7. Using Euler’s formula, find the unknown:

Solution:

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

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 Euler’s formula, which is stated as, F + V – E = 2

For the given polygon,

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

Therefore, A polyhedron is not possible as Euler’s formula is not satisfied.
