Cubo perfecto mayor que un número dado

Dado un número N, la tarea es encontrar el siguiente cubo perfecto mayor que N.
Ejemplos: 

Input: N = 6
Output: 8
8 is a greater number than 6 and
is also a perfect cube

Input: N = 9
Output: 27

Acercarse: 

1. Encuentre la raíz cúbica de N dada.
2. Calcule su valor mínimo utilizando la función de suelo en C++ .
3. Luego súmale 1.
4. Imprime el cubo de ese número.
