Important Topics for NCERT Maths Exemplar Solutions Chapter 6 – Visualizing Solid Shapes


With the help of NCERT Exemplar Class 8 for Maths Exemplar problems with solutions, you will get to know about the polyhedrons. Any solid that is constructed of only polygonal faces is termed as a polyhedron. The faces of this kind of solid meet at edges which are the line segments. The point at which these edges meet is called the vertex. 

You will also learn about Euler’s formula for polyhedron which is F + V – E = 2. Here F denotes the number of faces of the polyhedron, V denotes the number of vertices for it and E denotes the number of edges. 

Types of Polyhedron 

Now that you are familiar with the concept of a polyhedron, you will also learn about their different kinds. Some of these kinds are –

  • Convex Polyhedron – polyhedrons that have all the faces towards the outside are known as convex polyhedrons. 
  • Regular Polyhedron or Platonic Solids – in case if the faces of the polyhedron are regular polygons which are congruent in nature; they are termed as the Regular Polyhedron. A cube is the perfect example of a regular polyhedron as all its sides are regular and congruent squares. 
  • Prism – a prism is also a polyhedron. In the case of a prism, its bottom and top faces are congruent polygons and its faces are known as lateral faces and parallelograms. 
  • Pyramid – a pyramid also falls under the category of a polyhedron. Its base is a polygon and its lateral faces are triangles.

The Surface Area of a Three-Dimensional Object 

In NCERT Exemplar for Class 8 Maths Chapter 6, you will learn about the surface area of a three-dimensional object and the basic rules while calculating it. Each figure has a different scenario in terms of the surface area of its constituent shapes and this concept is dealt with in the chapter with the help of diagrams and examples. 

Exercise Discussions of NCERT Maths Exemplar Solutions Class 8 Chapter 6 – Visualizing Solid Shapes

  • The exercise begins with a multiple choice question and you are given four options with each of the questions. For instance, the very first question has four different figures given as the options and the question enquires which of them can be classified as a polyhedron.
  • There are true-false questions and fill in the blanks questions added in the exercise too. These questions are based on very simple calculations and understanding of the chapter. 
  • There are diagram based exercises where you are provided with certain values and you need to observe the figure and provide answers to it. For example question number 24, where you are provided with a figure and you need to write about the number of faces that meet at point B.
