7.3.2.Define function to accept three int parameters

#include <iostream> 

using namespace std; 

 

void box(int length, int width, int height); // box()'s prototype 

 

int main() 

{ 

  box(7, 20, 4); 

  box(50, 3, 2); 

  box(8, 6, 9); 

 

  return 0; 

} 

 

void box(int length, int width, int height) 

{ 

  cout << "volume of box is " << length * width * height << "\n"; 

}

volume of box is 560
volume of box is 300
volume of box is 432
