The thickness of an 800 pages of book is 18mm. Calculate the thickness of one leaf of the book giving your answer in meters and in standard form

  • A 2.25 x 10-4m
  • B 50 x 10-4m
  • C 2.25 x 10-5m
  • D 4.50 x 10-5m

The correct answer is D. 4.50 x 10-5m

Let's solve this problem step by step. The thickness of an 800-page book is 18mm. Since one leaf of a book contains two pages, the book has 800/2 = 400 leaves. So, the thickness of one leaf of the book is 18/400 = 0.045 mm.

To convert this value to meters, we need to divide it by 1000: 0.045/1000 = 0.000045 m. In standard form, this value is 4.5 x 10^(-5) m.

So, the thickness of one leaf of the book is 4.5 x 10^(-5) m
