Atmospheric pressure on a book lying on a table

What is total downward atmospheric force on the top of a 0.21 m by 0.26 m book lying on a table? Why doesn't this force break the table?

Solution Preview

If the bottom surface of the book touches the surface of the table perfectly, then the downward atmospheric force on the book = Patm * Surface area of the book.

P atm = 10^5 N/m^2
Area = 0.21*0.26 m^2

Atm force = 10^5 * 0.21*0.26 N = 5460 ...
