Solution

Total number of books $= 5$
Thickness of 1 book $= 20 m m$

Total number of paper sheets $= 5$
Thickness of 1 sheet $= 0.016 m m$

Total thickness of 5 books $= 5 \times 20 = 100 m m$
Total thickness of 5 sheets $= 5 \times 0.016 = 0.08 m m$

So, the total thickness of the pack $= 100 + 0.08 = 100.08 m m$
