1.7.1.Use function in an expression
#include <iostream>  
using namespace std;  
  
double box(double length, double width, double height)// use double data  
  
int main()  
{  
  double sum;  
  
  sum = box(10.111.23.3+ box(5.56.67.7+ box(4.05.08.0);  
  
  cout << "The sum of the volumes is " <<  sum << "\n";  
  cout << "The average volume is " << sum / 3.0 << "\n";  
  
  return 0;  
}  
  
// This version of box uses double data.  
double box(double length, double width, double height)  
{  
  return length * width * height ;  
}
The sum of the volumes is 812.806
The average volume is 270.935
