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 = 20 x 5 = 100 mm
Thickness of one paper = 0.016 mm
Thickness of 5 papers = 0.016 x 5 = 0.08 mm
Total thickness of a stack = 100 + 0.08
= 100.08 mm
= 100.08 x 10²/10² = 100.08×10² mm
