Question

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 1

Answer:

100.08 mm

Step-by-step explanation:

1 book = 20 mm

5 books = 20 x 5 mm

5 books = 100 mm

1 paper sheet = 0.016 mm

5 paper sheets = 0.016 x 5

5 paper sheets = 0.08 mm

total thickness = 100 + 0.08 mm

total thickness = 100.08 mm

Answer 2

1.08mm

Step-by-step explanation:

(5×20mm)+(5×0.016mm)=1cm+0.08mm=1.08mm
