Pack a box of books

A standard shipping box is $18$ inches long $12$ inches wide $10\mathrm{.}5$ inches tall. A standard size hardcover coffee table book is $16$ inches long $10$ inches wide $1\mathrm{.}2$ inches thick. Books are stacked into the shipping boxes one on top of the other, with one inch padding on each side. In other words, one book plus side padding will exactly fit into the bottom of the box.

Your program will ask the user for the number of books the customer is ordering, and then compute how many standard boxes will need to be shipped.

Think about how you would solve this problem without a computer, and write down the steps you need to do so$($the algorithm$).$ Do NOT start typing code in without doing this step first! Next, translate that algorithm into a Python program. You should try to come up with the steps yourself, even though much of the program is already given to you in the starter code. Note the use of comments in your code to keep track of what is being done where.
