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 m3, and its expression is m3 = 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 23 = 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.
