Before doing anything we recommend you to do a math practice set. Then find out twenty math problems related to this topic and write those on a paper. Solve first ten math problems according to basic math formula. 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 go through our page for five digit cube and cube root shortcut trick. After this do remaining ten questions and apply shortcut formula on those math problems. Again keep track of Timing. This time you will surely see improvement in your timing. But this is not all you want. You need more practice to improve your timing more.

Few Important things to Remember

We all know that the most important thing in competitive exams is Mathematics. That doesn’t mean that other sections are not so important. But only math portion can leads you to a good score. A good score comes with practice and practice. The only thing you need to do is to do your math problems correctly and within time, and this can be achieved 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, other peoples may not do the same. Here we prepared five digit cube and cube root shortcut tricks for those people. We try our level best to put together all types of shortcut methods here. But it possible we miss any. We appreciate if you share that with us. Your help will help others.

Find Five 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. Some Examples are given in simplification on math paper there five to ten examples are given but cube numbers are given in mixed simplification examples.

We can easily calculate the cube of a Five digit numbers using this tricks.

 

Find Five Digit Cube and Cube Root Tricks

First of all you Need to remember cube of 1 to 10. 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.

13=1 [Ends with 1]

23=8 [Ends with 8]

33=27 [Ends with 7]

43=64 [Ends with 4]

53=125 [Ends with 5]

63=216 [Ends with 6]

73=343 [Ends with 3]

83=512 [Ends with 2]

93=729 [Ends with 9]

103=1000 [Ends with 0]

See, all the end digits of 1 to 10’s cube is different. So by seeing the last digit we can predict the cube root of that number.

Answer: Option (B)
How to Solve

  1. First of all check the last digit.
    In this case it is 6. So, we can predict that the Cubic number will ends with 6 (as 63 = 216). Note down 6.
  2. Now forget about the last three digits and Take first two digits for consideration.
    Here the first two digits are 17.
  3. Find out the nearest small Cubic value of the Number.
    In this case it is 2 (as 23 = 8). Note down 2 to the left of 6.
    So, We get our final answer 3√17576 = 26.

      Did you know this trick is only for perfect cube and did you know all the numbers ending with2,3,7 and 8 are not perfect cube

  1. Karun-Singhal says:

    At top of this page it is written that find cube and cube root of five digit but why you have told us only cube root why not cube

  2. Gourav says:

    while calculating cube root in 5th example you mentioned 46 is nearest to 3^3(27) while its nearest to 4^4(64)..
    why is it so??????

  3. Ajay Kumar says:

    Can you help us to find out the cube root for 14157 , 14158.
    By above detailed it should be like that for 14158.
    last digit 8*8*8 =512. we should take 2.
    considering first two digit 14 (14158)and the nearest cube will be 2 (2*2*2)=8<14. so the answer for 14158 is 22.
    This is wrong answer.
    same thing for 14157. Please check.
