Exercise 10.3

1. Can a polyhedron have for its faces
(i) 3 triangles?
(ii) 4 triangles?
(iii) a square and four triangles?
No, such polyhedrons are not possible. Such figures should have minimum 4 faces.
(ii) Yes, a triangular pyramid has 4 triangular faces.
(iii) Yes, as square pyramid has a 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).
it is possible, only if the number of faces is greater than or equal to 4.

3. Which are prisms among the following?

Solution.i) A nail: Not a polyhedron as it has a curved surface. This is not a prism.

ii) Unsharpened Pencil: it is a prism.

iii) A table Weight: It is not a prism.

iv) A Box: It is a prism

4.(i) How are prisms and cylinders alike?
   (ii) How are pyramids and cones alike?
 The prisms and cylinder, both, have their base and top faces as congruent and parallel to each other. Also, a prism becomes a cylinder as the number of sides of its base becomes larger and larger.

(ii) The pyramids and cones are alike in the sense that their lateral faces meet at a point (called vertex). Also, a pyramid becomes a cone as the number of sides of its base becomes larger and larger.

5. Is a square prism same as a cube ? Explain.
yes, a square prism can also be a cube. A square prism has a square as its base. However, its height is not necessarily same as the side of the square. Thus, a square prism can also be a cuboid.

6. Verify Euler’s formula for these solids

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                                                                                                                                                                         Verified.

Here F = 9
V = 9
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.

 Faces                                                                  ?520

Euler’s formula: F + V = E + 2
⇒ F + 6 = 12 + 2
⇒ F + 6 = 14
⇒ F = 14 – 6 = 8

Euler’s formula: F + V = E + 2
⇒ 5 + V = 9 + 2
⇒ 5 + V = 11
⇒ V= 11-5 = 6

Euler’s formula: F + V = E + 2
⇒ 20 + 12 = E + 2
⇒ 32 = E + 2
⇒ E = 32 – 2
⇒ E = 30

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