Can you find the thickness of a single page of your notebook or textbook using a scale? Think of a way and write it. Carry out the activity and report your result.
To find the thickness of a single page: Take a notebook or textbook and count the total number of pages.
Measure the total thickness of the book using a scale (excluding the cover). Divide the total thickness by the number of pages to get the thickness of one page.
For example, if a book with 200 pages has a total thickness of 20 mm, then thickness of one page = 20 mm ÷ 200 = 0.1 mm.
This method works because the thickness of a single page is too small to measure directly with a standard scale, but measuring multiple pages together gives a measurable value.
Explanation
The chapter mentions on Page 5 that 1 mm is the smallest value of length that can be measured using a standard scale. Since a single page is thinner than 1 mm, we cannot measure it directly. The method of measuring multiple pages together and dividing by the count is a practical way to find the thickness of thin objects.
Solution Steps
Count the total number of pages in the notebook or textbook.
Measure the total thickness of the book using a scale, excluding the cover.
Divide the total thickness by the number of pages to calculate the thickness of one page.
This method is necessary because a single page is too thin to be measured directly by a standard scale.
