Solution
No. Of books= 5
Thickness of each book= 20mm
No.of paper sheets= 5
Thickness of each paper sheets= 0.016mm
Total thickness of the stack= thickness of 5 books + thickness of 5 paper sheets
=5×20 + 5X.016
=100 + 0.080
=100.08 mm
The total thickness of the stack= 1.0008 × 10 ^2 mm
Thickness of each book= 20mm
No.of paper sheets= 5
Thickness of each paper sheets= 0.016mm
Total thickness of the stack= thickness of 5 books + thickness of 5 paper sheets
=5×20 + 5X.016
=100 + 0.080
=100.08 mm
The total thickness of the stack= 1.0008 × 10 ^2 mm
