Since we now know how to find the cube of a number using the cube formula, let us discuss how to find the cube root of a perfect cube. Understanding how to find square root of a number will help us understand how to find a cube root easily. We can apply the same method to find the cube root of any perfect cube. But here’s the best part — Finding cube root of a perfect cube is simpler than finding square root of a number.

Generally speaking, in the simplification section of the question paper of IBPS PO, IBPS Clerk, SBI PO, SBI Clerk, SSC CGL, SSC CHSL and other competitive exams, we are given to find cube roots of only perfect cubes. But if we are required to find the cube root of a number as part of a question from the approximation section, then it may or may not be a perfect cube.

### How To Find Cube Root Of A Number In Two Easy Steps

Firstly, you must memorise the cubes of numbers from 1 to 15.

We have already learnt that there is a certain pattern seen when it comes to cubes of numbers:

SMART METHOD

**How to find cube root of a perfect cube in a smart method is a 2-step process**

Example 1: Find ∛551368

Solution:

Step1: **Decide the unit’s place of the result.**

Step2: **Leave the last 3 digits and find the immediate perfect cube before the remaining number.**

**That is the number in our ten’s place**

__8__2

**∛551368 = 82**

Example 2: Find ∛50653

Solution:

Step1: **Decide the unit’s place of the result.**

Step2: **Leave the last 3 digits and find the immediate perfect cube before the remaining number.**

**That is the number in our ten’s place**

__37__

**∛50653 = 37**

Remember that knowing a technique is quite ineffective when it comes to applying them in the exam. To perfect these techniques and smart methods of finding cube root of a perfect cube, you must give it enough practice.
