Given:
In a stack, there are 4 books
Each book of thickness 24mm
6 paper sheets
Each sheet of thickness 0.015 mm
To Find:
What is the total thickness of a stack in standard form
Solution:
Number of books in stack = 4
The thickness of 1 book = 24mm
The thickness of 4 books = 24×4
= 96mm
Number of paper sheets in stack = 6
The thickness of 1 sheet = 0.015mm
The thickness of 6 sheets = 6×0.015mm
=0.09mm
Total thickness of stack = Thickness of 4 books +Thickness of 6 sheets
= 96+0.09
= 96.09mm
The total thickness of a stack in standard form = 9.609 × 10 mm
Hence, the total thickness of a stack in standard form is 9.609 × 10 mm
