In a stack there are 5 books each of thickness 20mm and 5 paper sheets each of thickness 0.016 mm. What is the total thickness of the stack.

Text Solution

Verified by Experts

Total number of books in the stack=5
thickness =20mm
Total thickness of the book =`20×5=100`
Total number of paper =5
thickness of the paper =`0.016mm`
Total thickness of the paper =`5×0.016=0.080`
Total thickness of the stack =`100+0.080=100.080=1.0008×10^2 mm`
