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.

Answer :

Thickness of 1 book = 20 mm
Thickness of 5 books = 5 x 20 mm = 100 mm
Thickness of 1 page = 0.016 mm
Thickness of 5 pages = 5 x 0.016 = 0.08 mm
Total Thickness = Thickness of 5 books + Thickness of 5 pages
Total Thickness = 100 + 0.08
Total Thickness = 100.08 mm
