# NCERT Solutions for Class 8 Maths Chapter 6 Exercise 6.1 Cubes and Cube Roots - PDF Download

NCERT solutions for class 8 maths chapter 6 ex 6.1 Cube and Cube Roots is about cubes of numbers and their relationship with the original numbers and the cubes of consecutive numbers. The students will learn about the odd and even properties of a cube, how to figure out the cube root, and the prime factor of a cube.

Class 8 maths chapter 6 exercise 6.1 NCERT solutions questions need to find the perfect cubes and also help the students understand how to multiply a number to get to the nearest perfect cube. The prime factors of any cube appear three times in the factors, so this property can be used to tell if a number is a cube or not.

Ex 6.1 class 8 maths solutions consists of 4 questions with its sub-parts. Class 8 maths ex 6.1 NCERT solutions are explained by our subject experts of maths for students to prepare well for the exam.

## Topics Covered in Exercise 6.1 Class 8 Mathematics Questions

Ex 6.1 class 8 maths chapter 6 NCERT solutions is based on the concepts of finding the perfect cube and cube roots which you can check below.

 1 Cubes Some interesting patterns Smallest multiple that is a perfect cube
1. Cubes - A cube is a three-dimensional shape with all of its sides equal.

If a cube has all sides equal to 1 cm, how many sides of 2 cm are needed to form a new cube?

8 such cubes are required, and what if we need to make a cube of side 3 cm with the cubes of side 1 cm? The numbers 1, 8, 27 ...etc can be shown below in the cube.

These are called perfect cubes or cube numbers. This means that we have the cube numbers by multiplying the number three times by itself.

• Some interesting patterns

1. Adding consecutive odd numbers - This proves that if you add the consecutive odd numbers, then you get a cube of the next number.

2. Cubes and their prime factors - The process of prime factorization is to find the prime factors of a number and then pairing them in a group of three. If you have all of the prime factors in a pair of three, then you have a perfect cube.

• Smallest multiple that is a perfect cube

Now that we know that the group of 3 prime factors creates a number perfect cube. We need to multiply it by the smallest multiple of that number to make it a perfect cube number.
