Question

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

Answer 1

Answer:

Explanation:

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
