## Find Seven digit Cube and Cube Root Tricks

Shortcut Tricks are very important things in competitive exam. Time is the main factor in competitive exams. If you know time management then everything will be easier for you. Most of us miss that part. We provide examples on Seven digit Cube and cube root shortcut tricks here in this page below. All tricks on seven digit cube and cube root are provided here. We request all visitors to read all examples carefully. These examples will help you to understand shortcut tricks on Seven digit Cube and cube root.

First of all do a practice set on math of any exam. Then find out twenty math problems related to this topic and write those on a paper. Do first ten maths using basic formula of this math topic. You also need to keep track of timing. After solving all ten math questions write down total time taken by you to solve those questions. Now practice our shortcut tricks on seven digit cube and cube root and read examples carefully. After doing this go back to the remaining ten questions and solve those using shortcut methods.

### Few Important things to Remember

You all know that math portion is very much important in competitive exams. It doesn’t mean that other topics are not so important. But only math portion can leads you to a good score. Only practice and practice can give you a good score. All you need to do is to do math problems correctly within time, and you can do this only by using shortcut tricks. But it doesn’t mean that without using shortcut tricks you can’t do any math problems. You may have that potential to do maths within time without using any shortcut tricks.

But, so many other people may not do the same. So Seven digit Cube and cube root shortcut tricks here for those people. Here in this page we try to put all types of shortcut tricks on Seven digit Cube and cube root. But it possible we miss any. We appreciate if you share that with us. Your little help will help others.

### Find Seven Digit Cube and Cube Root Tricks

Cube and Cube Root both are very important in any competitive exams. Without remembering this you can’t survive in exam hall. As all competitive exams are very tightly bound with time, so you don’t have much time to spend on calculating cubes.

We can easily calculate the cube of a Seven digit cube and cube root numbers using this tricks.

First of all you Need to remember cube of 1 to 15. This is so easy for any one. It will help you to obtain the cube and cube root of any numbers very easily. You can tell the cube root of a number by seeing only the last digit of the Number.

1^{3}=1 [Ends with 1]

2^{3}=8 [Ends with 8]

3^{3}=27 [Ends with 7]

4^{3}=64 [Ends with 4]

5^{3}=125 [Ends with 5]

6^{3}=216 [Ends with 6]

7^{3}=343 [Ends with 3]

8^{3}=512 [Ends with 2]

9^{3}=729 [Ends with 9]

10^{3}=1000 [Ends with 0]

11^{3}=1331 [Ends with 1]

12^{3}=1728 [Ends with 8]

13^{3}=2197 [Ends with 7]

14^{3}=2744 [Ends with 4]

15^{3}=3375 [Ends with 5]

See, all the end digits of 1 to 15’s cube is different. So by seeing the last digit we can predict the cube root of that number.

### Example #1 – Seven digit Cube and Cube Root Tricks

^{3}√3869893 = ?

- 147
- 150
- 154
- 157

**Answer:**Option (D)

**How to Solve**

- First of all check the last digit.

In this case it is 3. So, we can predict that the Cubic number will ends with 7 (as 7^{3}= 343). Note down 7. - Now forget about the last three digits and Take first four digits for consideration.

Here the first four digits are 3869. - Find out the nearest small Cubic value of the Number.

In this case it is 15 (as 15^{3}= 3375). Note down 15 to the left of 7.

So, We get our final answer^{3}√3869893 = 157.

**Answer:**Option (A)

**How to Solve**

- First of all check the last digit.

In this case it is 0. So, we can predict that the Cubic number will ends with 0 (as 10^{3}= 1000). Note down 0. - Now forget about the last three digits and Take first four digits for consideration.

Here the first four digits are 1728. - Find out the nearest small Cubic value of the Number.

In this case it is 12 (as 12^{3}= 1728). Note down 12 to the left of 0.

So, We get our final answer^{3}√1728000 = 120.

- 131
- 132

Show Answer Show How to Solve Open Rough Workspace

**Answer:**Option (C)

**How to Solve**

- First of all check the last digit.

In this case it is 1. So, we can predict that the Cubic number will ends with 1 (as 1^{3}= 1). Note down 1. - Now forget about the last three digits and Take first four digits for consideration.

Here the first four digits are 2248. - Find out the nearest small Cubic value of the Number.

In this case it is 13 (as 13^{3}= 2197). Note down 13 to the left of 1.

So, We get our final answer^{3}√2248091 = 131.

How to find the square root of more than 5 digit number

WOOOOOOOOOOOOOOOOOO AWESOME SITE I LOVE IT

can you please explain how to solve cube of large numbers. Is there any shortcut for it?

check the cube and cube root short cut trick page where u find 5 to 6 digit cube root tricks

if cube is not perfact cube then our solution may be wrong or there is any way….

great sir, simply great

Very easy to understand, but how to find out 6 to 5 digit cube.

how to find cube root of 8 digit no.

It’s Easy Vani. Divide 8 digits number in two parts same like in 7 digits number. One part of 3 digits and another part of 5 digits. And apply the same trick.

Exa. Cube root of 34328125

125=5 And Cube root of 3432 is nearly of 32. So Answer = 325.

But in 8 digits number you have to remember the cube of 11 to 46.

this is very useful of mine so thanks a lot ,my small request to u some simplification shortcuts added them

really super …..everyone must learn…maths is not difficult but fun….!!!!

Its realy good for all.

But..’ i want to know that what is the tric for 21-30,40,50 qubes

REALLY SO EASY TRICK

THANK U SO MUCH

very nice…
