A box contains 5 books and 5 cards which are of thickness 20 mm and 0.016 mm respectively. Find the total thickness

The correct answer is: Total thickness is 100.08 mm.

Step-by-step solution:-
Thickness of books = Thickness of each book × number of books
= 20 mm × 5
= 100 mm ............................................................. (Equation i)
Thickness of cards = Thickness of each card × number of cards
= 0.016 × 5
= 0.08 mm ........................................................... (Equation ii)
Total thickness = thickness of books + thickness of cards
Total thickness = 100 + 0.08
Total thickness = 100.08 mm
Final Answer:-
∴ Total thickness is 100.08 mm.
