In a stack, there are 5 books each of thickness 20mm and 5 paper sheets each of thickness 0.016mm. What is the total thickness of the stack?
Thickness of 1 book =20 mm
Thickness of 5 book =20×5=100 mm --------------(i)
Thickness of 1 paper =0.016 mm
Thickness of 5 paper =0.016×5=0.08 mm ---------(ii)
Total Thickness = (i) + (ii)
=(100+0.08) mm
=100.08 mm
=1.0008×102 mm
