Question

The pages of a book are numbered 1 to 200 and each
leaf is 0.10mm thick. If each cover is 0.20 mm thick, what
is the thickness of the book?

Answer 1

Answer:

10.4mm

Explanation:

2 pages = 1 leaf

200 pages = 100 leaves

100 × 0.10 = 10 mm thickness

Total thickness = 2(0.20) +10 = 0.4+10 = 10.4mm
