Question

in a pack there are 5 books each of the next 20 mm and 5 paper sheets each of thickness 0. 016 mm what is a total thickness of the pack

Answer 1

thickness of each book = 20 mm

∵ thickness if 5 book = 5*20 mm = 100 mm

thickness of each sheet = 0.016

∵ thickness of 5 paper sheet = 5*0.016 mm = 0.080

total thickness of pack = thickness of 5 paper sheet + thickness of 5 book

= 0.080 + 100 mm

= 100.08

= 1.0008*10²
