1. Write a program that calculates the area of a box. Allow the user to enter the
   height, width, and length of the box.


2. Modify the program in exercise 1 to calculate the cost of shipping the box. Assume
   that the cost is based solely on the number of cubic units of the box. If the box is
   under 100 cubic units, the cost is $5. If it is over 100 and less than 1000 units, it is
   $10. If it is over 1000 units, it is $20. Create the function to use a default value of
   $20.


3. Specify the function that calculates the area of the box to be inline.
