We have,

[ ³√k ] = 1 , when k varies from 1 to 7

[ ³√k ] = 2 , when k varies from 8 to 26

[ ³√k ] = 3 , when k varies from 27 to 63

and so on.

From here, we can solve the problem.

I'm posting a similar problem which came to my mind. I don't know whether it has been already discussed or not. Let me know if it has been.
