#### Information on cubes and cube roots

In daily mathematics, such as powers and exponents or to find a three-dimensional cube’s side when its volume is known, cubes and cube roots are used. Numerous exercise problems are understood in this PDF of RS Aggarwal Solutions for Class 8 Chapter 4, which enhances awareness of the ideas. Additionally, the Maths RS Aggarwal Class 8 Solutions Chapter 4 provided here will assist you in developing critical thinking skills and familiarity with a variety of problem-solving techniques.

##### Cubes

Cube numbers or perfect cubes are the results of multiplying a number three times by itself. Examples include: 1, 8, 27,…, etc.

- The natural number m’s cube is represented by the symbol m
^{3}, and its expression is m^{3}= m x m x m. - Thus, 1³ = 1 × 1 × 1 = 1
- 2³ = 2 × 2 × 2 = 8
- 3³ = 3 × 3 × 3 = 27, and so on.

##### Some Interesting Patterns

Any integer is a perfect cube if, when it is divided into its prime factors, each prime factor appears three times.

As an example, the number 216 = 2 x 2 x 2 x 3 x 3 x 3 = 23 x 33 = (2 x 3)3 = 63, which is a complete cube.

- The smallest multiple that is a perfect cube
- Typically, in order to transform a number into a perfect cube, we must determine the smallest natural number by which it may be multiplied or divided.

##### Cube Roots

Finding the cube is simply the inverse operation of finding the cube root.

- The cube root of 8 is 2
^{3}= 8. - The cube root is represented by the symbol. Thus,∛8 = 2

##### How to find a cube number’s cube root

- Obtain the specified number. Starting with the digit on the right side of the number, begin creating groups of three digits.
- The relevant cube root (unit) digit will be provided by the first group.
- Take the following parties then. Find the closest cube numbers that contain this group. Replace the lower value with one and the necessary cube root with ten.
