Output 1 :
Enter side of cube                                             : 6
Volume = 216
Enter radius and height of cylinder            : 3 4
Volume = 113.040001
Enter lenght,breadth,height of rectangle : 2 3 7
Volume = 42

Output 2 :
Enter side of cube                                          : 3
Volume = 27
Enter radius and height of cylinder           : 4 3
Volume = 150.720001
Enter lenght,breadth,height of rectangle : 4 2 8
Volume = 64
