# 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
