One way to solve this is:

5 shelves * 234 cm each = 1170 cm

1170 cm / 4.5 cm per book = 260 books

Another approach would be to determine how many books fit on ONE shelf, and then multiply by 5 to get the total:

234 cm per shelf / 4.5 cm per book = 52 books per shelf

(52 books per shelf)(5 shelves) = 260 books
