Class 8 Maths Chapter 1 Notes What is A Square and A Cube?

A Square and A Cube is the first chapter of CBSE Class 8 Maths Notes. It introduces the concepts of squares and cubes of numbers and explains their properties.

The chapter also covers perfect squares, perfect cubes, square roots, cube roots, and methods used for finding roots. Understanding these concepts helps in developing numerical skills and provides a foundation for learning advanced mathematical topics in higher classes.

Square

→ A square is a value that you get
when you multiply a number by
itself.

→ The square of a number x is x2.
Example: Square of 8 is 64. This
means 8 multiplied by 8 to give 64.
82 = 8 × 8 = 64

→ Square numbers are always
positive.
