RS Aggarwal Solutions for Class 8 Maths Chapter 19 Exercise 19.2 (Ex 19B)
Below we have provided RS Aggarwal Solutions for Class 8 Maths Chapter 19 Exercise 19.2 Three Dimensional Figures -(Question 1) Define Euler’s relation between the number of faces, number of edges and number of vertices for various 3-dimensional figures.
Solution:
In a 3-dimensional figure, let the number of faces be F; the number of edges be E and the number of vertices be V. Then, the Euler’s relation is given byF – E + V = 2
(Question 2) How many edges are there in a
(i) Cuboid = 12 edges (ii) Tetrahedron = 6 edges (iii) Triangular prism = 9 edges (iv) Square pyramid = 8 edges(Question 3) How many faces are there in a
(i) Cube = 6 faces (ii) Pentagonal prism = 7 faces (iii) Tetrahedron = 4 faces (iv) Pentagonal pyramid = 6 faces(Question 4) How many vertices are there in a
(i) Cuboid = 8 vertices (ii) Tetrahedron = 4 vertices (iii) A triangular prism = 10 vertices (iv) A square pyramid = 5 verticesBenefits of RS Aggarwal Solutions for Class 8 Maths Chapter 19 Exercise 19.2
