Question

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

Answer 1

200 pages means that there are 100 papers.

1 paper = 0.1mm
So, 100 papers = 0.1 * 100 = 10mm

There are two covers of 0.2mm each, therefore

Total thickness = 10 + 2*0.2
= 10 + 0.4
= 10.4mm
