Learning the cubes from 1 to 10 will help a lot.

1) A number having any zero at the end will have 3 more zeroes in its cube. Eg- 10=1000

2)To find the units digit of cube of a number, you need to check the units digit of the cube of the units digit of the number that has to be cubed. Eg- cube of 343 will have 7 at its unit place because 3's cube is 27 and its unit digit is 7.
