   // member variables
   <access specifier> <data type> variable1;
   <access specifier> <data type> variable2;
   ...
   <access specifier> <data type> variableN;
   // member methods
   <access specifier> <return type> method1(parameter_list) {
      // method body
   }
   <access specifier> <return type> method2(parameter_list) {
      // method body
   }
   ...
   <access specifier> <return type> methodN(parameter_list) {

      Box1.length = 6.0;
      Box1.breadth = 7.0;
      // box 2 specification
      Box2.height = 10.0;
      Box2.length = 12.0;
      Box2.breadth = 13.0;
      // volume of box 1
      volume = Box1.height * Box1.length * Box1.breadth;
      Console.WriteLine("Volume of Box1 : {0}",  volume);
      // volume of box 2
      volume = Box2.height * Box2.length * Box2.breadth;
      Console.WriteLine("Volume of Box2 : {0}", volume);
