Here we have provided the solutions for Class 8 Maths Exercise 10.3.
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 a minimum of 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 a square shape at its base. However, its height may 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:
Faces | ? | 5 | 20 |
Vertices | 6 | ? | 12 |
Edges | 12 | 9 | ? |
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.

What is the shape of a pyramid that we have all seen? Conical! That’s correct. What about soccer? What is the football’s shape? You’d call it spherical? You’re correct once more. What are these shapes, exactly? This is a solid shape. We’re visualising solid shapes, to put it simply. As a result, you’ll learn more about visualising solid shapes in this chapter.
