That tiny box contains 18 pounds (8.16 kg) of super-compacted books, you can imagine its physical density must be very high. (Re: Density = Mass (kg) per unit volume (metre^3) ) You can smash someone's head with that small box like a big piece of brick.

And, the information density is high too. Think how 74 chapters, 18 study sessions, 6 months of study can stuff inside 18 pounds of books and inside a tiny small box.

That's why they offer the choice of intangible and weightless ebook over the heavy brick.
