A textbook is 5.41 cm thick including the covers. In a bookstore display, how many of these books could be placed upright on a shelf 2.7 m long?

Answer 1

To get things in the same unit of measure, convert 5.41 cm to meters:

(2.7 m)/(0.0541 m) = 49.9 therefore 49 books will fit on the shelf with a little room left over. There is not quite enough room the book # 50.
