No. Of books = 10
Thickness of each book= 25 mm
No.of paper sheets= 8
Thickness of each paper sheets= 0.017 mm
Total thickness of the stack= thickness of 5 books + thickness of 5 paper sheets.
= 10 * 25 + 8 * 0.017
= 250 + 0.136
= 250.136
= 2.50136 * 10²
The total thickness of the stack = 2.50136 * 10² mm.
