Express the number appearing in the following statement in standard form.
Thickness of a thick paper is 0.07 mm.
In a stack there are 5 books each of thickness 20 mm and 5 paper sheets each of thickness 0.016 mm. What is the total thickness of the stack?
∵ Thickness of one book = 20 mm
∴ Thickness of 5 books = 
mm
= 100 mm
Again,
Thickness of 1 paper sheet = 0.016 mm
∴ Thickness of 5 paper sheets = 5 
0.016 mm
= 0.080 m
∴ Total thickness = 100 mm + 0.080 mm
= 100.08 mm
