You also learn in class that one kilobyte of computer memory will hold about 2/3 of a page of typical text (without formatting). a typical book has about 400 pages. how many such books can a 9-gig flash drive hold?

The flashdrive can hold 35389 400-pages-books

Explanation:

If of a page occupies 1 kB of memory, we can calculate how much memory a book will take

Now that we know that a book average file size is about 266,67 kB, we calculate how many of them can a 9 GB flash drive hold.

To do the calculation, we have to know how many kilobytes are in 9 gigabytes.

There is 1024 kilobytes in a megabyte, and 1024 megabytes in a gigabyte, so:

Finally, knowing the average file size of a book and how much memory in kilobytes the 9 GB flash drive holds, we calculate how many books can it hold.

The flashdrive can hold 35389 400-pages-books, or 14155776 pages of typical text.
