the thickness of a brand of paper is about 0.000 000 05 cm.How many pieces of paper are there in a 30 cm stack?
--------------
0.000 000 05 cm = 5.0*10^-8 cm thick
# = 30 cm/5*10^-8 cm
= 6*10^8 sheets
or 600,000,000 sheets
-------------------
That's some really thin paper. A sheet is typically 0.003" - 0.004", or ~0.008 cm. A 30 cm stack would be 3,750 sheets.
