The contents of a single CD-ROM are roughly equivalent to about how many books?

Explanation:
Estimating how much text a CD-ROM can hold compared with printed books. A standard CD-ROM stores about 650–700 megabytes of data. If you think of a typical book’s text stored as plain text (without heavy images), it takes only a few hundred kilobytes to a couple megabytes, depending on length and formatting. Dividing the CD’s capacity by a rough per-book size gives a few hundred books’ worth of text. With real-world formatting and any graphics or embedded material, that number settles to around 300 books. That’s why 300 is the best rounded estimate for how many books a single CD-ROM can contain.
