**Maths Ace Class 8 Solutions Chapter 13 Representing Solids on a Plane**

Welcome to NCTB Solutions. Here with this post we are going to help 8th class students for the Solutions of Maths Ace Prime Class 8 Math Book, Chapter 13, Representing Solids on a Plane. Here students can easily find step by step solutions of all the problems for Representing Solids on a Plane, Exercise 13.1 and 13.2 Also here our mathematics teacher’s are solved all the problems with easily understandable methods with proper guidance so that all the students can understand easily. Here in this post students will get chapter 13 solutions.

**Representing Solids on a Plane Exercise 13.2 Solution :**

**Question no – (1) **

**Solution : **

Number, because it does not satisfy Euler’s formula

V + F – E = 2

= 14 + 10 – 20

= 24 – 20

= 4 ≠ 2

**Question no – (2) **

**Solution : **

Faces |
edges |
vertices |
||

(a) |
Tetrahedron | 4 | 6 | 4 |

(b) |
Rectangular pyramid | 5 | 8 | 5 |

(c) |
Pentagonal prism | 7 | 15 | 10 |

(d) |
Octahedron | 8 | 12 | 6 |

**Question no – (3) **

**Solution : **

By formula,

= V – E + F = 2

= 12 – E + 10 = 2

= -E = 2 – 22

= -22

= E = 20

Therefore, Edges in the polyhedron will be 20
