#include <iostream>

using namespace std;



float cube_number(float num);



int main()

{

  float number;

  float number3;

  cout << "Please enter a number \n";

  cin >> number;

  

  number3 = cube_number(number);

  cout << number << " cubed is " << number3;



  return 1; 

}



float cube_number(float num)

{

  float answer;



  answer = num * num * num;

  return answer;

}

Please enter a number
123
123 cubed is 1.86087e+006"
