return 2*(height*width)+2*(height*length)+2*(width*length);
}
}

// Main.java

public class Main
{
public static void main (String[] args)

Box b1 = new Box();
Box b2 = new Box();

b1.setBox(3,4,5);
b2.setBox(6,7,8);
  
System.out.println("The area of box1 is " + b1.area());
System.out.println("The area of box2 is " + b2.area());
}
}
