## Find Five digit Cube and cube root Tricks

**Need to remember 1 to 10 cube** and this so easy for any one.

**Example 1:**

^{3}√**13**824 = ?

**Answer :**

**Step 1: **Last digit of cube number from right side is 4 that we consider 64 = 4^{3} we put down 4. Then

**Step 2:** Take the number whose cube is nearest to 13.

That is 13 is nearest to 2^{3} and 3^{3} we take small one cube digit that is 2.^{3}√**13**824

So the answer is **24.**

**Example 2:**

^{3}√**15**625= ?

**Answer :**

**Step 1:** Last digit of cube number from right side is 5 that we consider 125 = 5^{3} we put down 5. Then

**Step 2: **Take the number whose cube is nearest to 15.That is 15 is nearest to 2^{3} and 3^{3} we take small one cube digit that is 2.

So the answer is **25.**

**Example 3:**

^{3}√**42**875= ?

**Answer :**

**Step 1:** Last digit of cube number from right side is 5 that we consider 125 = 5^{3} we put down 5. Then

**Step 2:** Take the number whose cube is nearest to 42.That is 42 is nearest to 3^{3} and 4^{3} we take small one cube digit that is 3.

So the answer is **35.**

## Find Seven digit Cube and cube root Tricks

Need to remember 1 to 20 cube and this so easy for any one.

**Example 1:**

^{3}√3869893 = ?

**Answer :**

**Step 1:** Last digit of cube number from right side is 3 that we consider 343 = 7^{3} we put down 7. Then

**Step 2: **Take the number whose cube is nearest to 3869.That is 3869 is nearest to 15^{3} and 16^{3} we take small one cube digit that is 15.

^{3}√3869893

So the answer is **157.**

**Example 2:**

^{3}√1728000 = ?

**Answer :**

**Step 1:** Last digit of cube number from right side is 0 that we consider 1000 = 10^{3} we put down 0. Then

**Step 2: **Take the number whose cube is nearest to 1728.That is 1728 is nearest to 12^{3} and 13^{3} we take small one cube digit that is 12.

^{3}√3869893

So the answer is **120.**

## Shortcut to find cuberoot of any 5 or 6 digit number

Shortcut to find cube root is especially helpful in competitive exams where every second counts.

By using this method you can save a lot of time and also get accurate results.

**Shortcut to mentally find the cube root of any 5 or 6 digit number**

Step 1:Find the cube root of the last digit.

Points to be remembered while using this method.

(1)If the last digit is 8 then cube root will be 2.

(2)If the last digit is 2 then cube root will be 8.

(3)If the last digit is 7 then cube root will be 3.

(4)If the last digit is 3 then cube root will be 7.

(5)If the last digit is any other digit other than 2,8,3,7 then put the same number.

From this step you will get the unit’s or one’s place digit.

**To find the tenth place digit you need to follow the below steps.**

Step 3: find the nearest cube of the remaining number.

Step 4: find the cube root of the nearest cube which will give you ten’s place digit.

List of cubes to be memorized

1^{3}=1 4^{3}=64 7^{3}=343

2^{3}=8 5^{3}=125 8^{3}=512

3^{3}=27 6^{3}=216 9^{3}=729

NOTE: Shortcut to find cuberoot of any 5 or 6 digit number is applicable only if the given number is a perfect cube.

You can verify whether the given number is a perfect cube or not by using the Prime Factorization Method. If you are not familiar with this method check it here.

Let me explain this with an example to make things more clear and easy to understand.

So lets say we want to find the cube root of a 6 digit number 15746

**Example 1:Find the cube root of 157464 in 5 seconds.**

∛157464=?

Step 1:First we need to find the cube root of the last digit of the given number.

Here the last digit is 4 . 4 is a number other than 2, 8, 3, 7

hence we put the number as it is.

We get our one’s place digit as **4**.

Now to get tenth place digit

Step 2: We need to strike the last 3 digits of the given number.

In this example the last 3 digits are 464 which we will strike off as shown below

157464

**5.**

**54**

**Ans:54**
