In a stack there are 5 books each of thickness 20 mm and 5 paper sheet

1.	In a stack there are 5 books each of thickness 20 mm and 5 paper sheets each of thickness 0.016 mm. What is the total thickness of the stack?
Answer» Thickness of each book = 20 mm Hence, thickness of 5 books = (5 × 20) mm = 100 mm Thickness of each paper sheet = 0.016 mm Hence, thickness of 5 paper sheets = (5 × 0.016) mm = 0.080 mm Total thickness of the stack = Thickness of 5 books + Thickness of 5 paper sheets = (100 + 0.080) mm = 100.08 mm = 1.0008 × 10² mm

In a stack there are 5 books each of thickness 20 mm and 5 paper sheets each of thickness 0.016 mm. What is the total thickness of the stack?

Answer»

Thickness of each book = 20 mm

Hence, thickness of 5 books = (5 × 20) mm = 100 mm Thickness of each paper sheet = 0.016 mm

Hence, thickness of 5 paper sheets = (5 × 0.016) mm = 0.080 mm

Total thickness of the stack = Thickness of 5 books + Thickness of 5 paper sheets

= (100 + 0.080) mm

= 100.08 mm

= 1.0008 × 10² mm
