NCERT Solutions for Class 8 Maths Visualizing Solid Shapes- We live in a 3-Dimensional world. Every object we can see or touch has three dimensions that can be measured by length, width, and height. For example, the room can be described by 3-dimensions length, width, and height. The NCERT Solutions for Class 8 Maths Visualizing Solid Shapes are prepared and explained by the maths experts to help the students to clear their doubts.
In Chapter 10 Visualizing Solid Shapes we will study about solid objects for example cubes, cuboids, cones, spheres, hemispheres etc. We already learn about the basic geometry in which basic shapes like a circle, a rectangle, square or rhombus measured by length and width. In NCERT Class 8 Maths Chapter 10 Visualizing Solid Shapes we also learn how to look 3-dimensional object differently from different positions so they can be drawn from different angles. For example, look at the different views of the brick.
Let's try to visualize a few more shapes your self.
For example: Take a cylinder. What is the side view of it? Is circular? Now take bangles of the same size and hold them together. Is it looks like a cylinder?
from the above-mentioned activity, we observed that when we hold a few bangles which are circular in shape with small thickness together we obtained a hollow cylinder.
In this NCERT solutions for class 8th chapter 10- Visualizing solids shapes, there are 3 exercises with 16 questions in them.

Tabulate the number of faces, edges and vertices for the following polyhedrons: (Here ‘V’ stands for number of vertices, ‘F’ stands for number of faces and ‘E’ stands for number of edges).
Solid | F | V | E | F+V | E+2 |
---|---|---|---|---|---|
Cuboid | |||||
Triangular pyramid | |||||
Triangular prism | |||||
Pyramid with square base | |||||
Prism with square base |
What do you infer from the last two columns? In each case, do you find
, i.e., ? This relationship is called Euler’s formula.
In fact this formula is true for any polyhedron.
8. Can a polyhedron have 10 faces, 20 edges and 15 vertices?
3. Draw a map of your school compound using proper scale and symbols for various features like play ground main building, garden etc.
