The minimum thickness of the book would simply be the sum of the thickness of the two cover pages and all the pages in between. That is:

minimum thickness = 0.9 mm * 2 + 0.13 mm * 400

minimum thickness = 53.8 mm

Answer:

Step-by-step explanation:

0.9 UB=0.95

0.9 LB=0.85

0.13 UB= 0.135

0.13 LB= 0.125

0.85x2=1.7

0.125x400=50

1.7+50=51.7

Minimum thickness=51.7mm
