{
    public class room
    {
       public int length;
      public  int breadth;
        public room()
        {
            Console.WriteLine("enter length");
            length = int.Parse(Console.ReadLine());
            Console.WriteLine("enter breadth");
            breadth = int.Parse(Console.ReadLine());
        }


        public int area()
        {
            return (length * breadth);
        }
    }
    public class bedroom : room
    {
        int height;
        public bedroom()
            : base()
        {
            Console.WriteLine("enter height");
            height = int.Parse(Console.ReadLine());
        }
        public int volume()
        {
