Answer 2

Answer:

min. thickness of the book is 53.8mm

Step-by-step explanation:

400 pages, each page thickness = 0.13mm

front and back cover thickness = 0.9mm

total thickness of the book = front + 400 pages + back cover

total = 0.9 + (400 x 0.13) + 0.9

total = 0.9 + 52 + 0.9

total = 53.8 mm
