Cube finding trick:

Hi everyone,

I am going to tell you a method for finding cubes of any number between 21 to 199 in just 3 simple steps and you keep practising then tou will find cube in just 30 seconds.

The one thing you must do is you have to remember the cubes from 2 to 19.

2 : 8

3 : 27

4 : 64

5 : 125

6 : 216

7 : 343

8 : 512

9 : 729

10: 1000

11: 1331

12: 1728

13: 2197

14: 2744

15: 3375

16: 4096

17: 4913

18: 5832

19: 6859

Step 1:

-------

Consider we have to find cube of 126

(ab)³000

-------x

00000c³

_______

_______

write the cube of (ab) then write three zeros after that cube..

for example in our number 126, (ab) is 12 and c is 6. So here we write the cube of 12 that is 1728 & cube of 6 like

1728000

??????x

0000216

________

________

Step 2:

-------

Now in the second row, we are gonna put the result of below formula

abc× {(ab)×c×3}

=126×{12×6×3}

=126×216

=27216

1728000

027216x

0000216

________

________

Step 3:

-------

Now everything has done and it's time to add the numbers of the formula

1728000

027216x

0000216

_______

2000376

so if you like this method, try at home and I am sure you will surprised yourself by doing it in 30 seconds after one or two days of practising.
