Step-by-step explanation:
Given:
Number of books = 10
Thickness of each book= 25mm
Total Thickness = 25×10 = 250 mm
Number of paper sheets= 8
Thickness of each sheet = 0.017 mm
Total Thickness = 8×0.017= 0.136 mm
Stack has books of Total width 250 mm and Sheets of Total width 0.136mm
The Thickness of the stack will be the sum of Thickness of books and sheets
= 250 + 0.136mm = 250.136 mm
