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 = 73 we put down 7. Then
Step 2: Take the number whose cube is nearest to 3869.That is 3869 is nearest to 153 and 163 we take small one cube digit that is 15.
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 = 103 we put down 0. Then
Step 2: Take the number whose cube is nearest to 1728.That is 1728 is nearest to 123 and 133 we take small one cube digit that is 12.
So the answer is 120.


Example 3:
3√2248091 = ?
Answer :
Step 1: Last digit of cube number from right side is 1, we put down 1. Then
Step 2: Take the number whose cube is nearest to 2248. That is 2248 is nearest to 133 and 143 we take small one cube digit that is 13.
So the answer is 131.
