you can find the list of perfect cubes on google
there are 12 between 1 and 1800
how many numbers between 1 and 1800 are perfect cubes that don't have the digit 5 or 0?
4 answers
12^3 = 1728
13^3 = 2197
so you only have to check the numbers from 1-12, and you know you can throw out 5 and 10 right away.
so, what do you get?
