How to remember the cube of numbers

Like my previous post, How to remember the squares of numbers, the technique to remember the cube of numbers requires some dedication. You have to know the cube of the previous number in order to know the cube of the next numbers (with this technique).

Firstly, know the cube of the previous number. Then, add 3 times the product of the previous number and the current number to the cube root of the previous number, then add 1. This will give you the cube of the required number.

1³ = 0+3*0*1+1 = 1
2³ = 1+3*1*2+1 = 1+6+1 = 8
3³ = 8+3*3*2+1 = 8+18 = 27
4³ = 27+3*3*4+1 = 27+36+1 = 64
5³ = 64+3*5*4+1 = 64+60+1 = 125
6³ = 125+3*5*6+1 = 125+90+1 = 216

and so on..
