**CBSE Class 8 Maths Chapter 11 – Visualising Solid Shapes NCERT Solutions**

In NCERT solutions for class 8 maths chapter 10, you will study a brief introduction to visualizing solid shapes, recognizing 2D, 3D shapes, maps, polyhedron, Convex Polyhedrons, Concave Polyhedron, Regular Polyhedron, non-regular polyhedron, prism, pyramid, verification of polyhedron by Euler’s formula.

**Sub-topics covered under Class 8 Maths Chapter 10**

- Ex. 10.1 – Introduction
- Ex. 10.2 – Views of 3D-Shapes
- Ex. 10.3 – Mapping Space Around Us
- Ex. 10.4 – Faces, Edges, and Vertices

**NCERT Solutions for Class 8 Maths Chapter 10 **

This chapter you will learn about visualizing solid shapes, views of 3d-shapes, mapping space and faces, edges and vertices. Let us now discuss the subtopics covered in this chapter.

**Ex. 10.1 – Introduction**

In this, you will learn about the concept of 2-D shapes like triangle, square, etc which have length and breadth, a 3-D object like cubes, cylinders, cones, spheres, etc which have length, breadth, height.

**Ex. 10.2 – Views of 3D-Shapes**

In this, you learn the concept of the 3-D shapes like cubes, cylinders, cones, spheres, etc and its different view from different sides i.e. the top view, front view, and side view and draw them on paper.

**Ex. 10.3 – Mapping Space Around Us**

In this you learn to represent different objects or place on a map at a particular scale and read a map by using the symbol of the objects, symbols are used to depict the different objects or places, maps involve a scale which is fixed for a particular map. A map depicts the location of a particular object/place in relation to other objects or places.

**Ex. 10.4 – Faces, Edges, and Vertices**

In this, you learn about the faces, edges, and vertices of the 3D polygons, prism, pyramids, polyhedron, types of the polyhedron, finding faces, edges and vertices of the polyhedron by Euler’s formula

**Some questions from NCERT SOlutions for Class 8 Maths Chapter 10**

**Q.1. Can a polyhedron have 10 faces, 20 edges, and 15 vertices? **

**Solutions:** Euler’s formula says,

*F*+*V**-E=*2

Here, *F *= 10

V = 15 *E= *20 So, *F*+*V – E*= 10 + 15 – 20 = 5 *+ *2

So, such type of polyhedron is not possible.

**Q.2. Using Euler’s formula find the unknown. **

Faces | ? | 5 | 20 |

Vertices | 6 | ? | 12 |

Edges | 20 | 12 | ? |

**Solution **

*F*+V=*E*+2

*F*+6+ 12 + 2

*F*=8

*F*+V=*E*+2 5+V = 9+2 *V *= 6

*F*+V*=E+*2 20+ 12 = *E*+2

*E**=*30
