Downloading the solution of Rs Aggarwal class 8 chapter 19 will help you in improving your weaker area so that you can score high marks in your mathematics paper. This chapter focuses on understanding the different 3D figures. This is not a very difficult chapter but you need to understand its concepts very well.
But first, let’s talk in detail about these threedimensional figures that you have to learn in this chapter. A threeDimensional figure or 3D figure can be defined as a structure that has three dimensions height, length, and width.
Different types of 3D figures are
 Cube A figure can be called a cube if it has 6 faces, 12 edges, and 8 vertices.
 Cuboid A figure can be called a cuboid if it has 6 faces, 12 edges, and 8 vertices.
 Triangular prism A figure can be called a triangular prism if it has 5 faces, 9 edges, and 6 vertices.
 Square pyramid A figure can be called a square pyramid if it has 5 faces, 8 edges, and 5 vertices.
 Pentagonal Pyramid A figure can be called a pentagonal pyramid if it has 6 faces, 10 edges, and 6 vertices.
 Tetrahedron A figure can be called a Tetrahedron if it has 4 faces, 6 edges, and 4 vertices.
Understanding some basic terms used in this chapter
 Vertices A vertice can be defined as a point where two or more lines, curves, or edges meet.
 Edges An edge can be defined as the line segment that joins two vertices.
 Face A face can be defined as a curve or flat surface on a 3d figure.
 Euler’s relation The formula said that any polyhedron has 2 more edges after summing up its total faces and vertices.
The chapter, Three Dimensional figures have 2 exercises that are discussed in detail below so that you know what topics are covered in this exercise and how the solution pdf of this chapter will help you in solving them.
