A book has a front and a back and 200 pages.

MariettaO [177]

Answer:

28.3mm

Step-by-step explanation:

upper bound of front and back cover=0.75mm and lower bound=0.65mm

lower bound of page=0.135mm and upper bound=0.145mm

As there is a front and back cover we multiply the lower bound by 2

as there is 200 pages we multiply the lower bound by 200

(0.65*2)+(0.135*200)=28.3mm
