Question

A book has a front and back and 400pages the front and back are 0.9mm thick to 1 decimal place and each page is 0.13mm thick to two decimal places calculate the minimum thickness of book

Answer 1

To calculate the minimum thickness of the book, we need to add the thickness of the front and back covers to the thickness of all the pages.

Step 1: Calculate the thickness of the front and back covers:

2 * 0.9 mm = 1.8 mm

Step 2: Calculate the thickness of all the pages:

400 pages * 0.13 mm/page = 52.0 mm

Step 3: Add the thickness of the front and back covers to the thickness of all the pages:

1.8 mm + 52.0 mm = 53.8 mm

Answer:

The minimum thickness of the book is 53.8 mm.
