HELP!You are handed a 8.0 cm stack of new one-dollar bills. Assume the thickness of a dollar bill is 1.4 times thicker than your textbook paper (textbook paper = 63 um). (that's "micrometers") How many dollars are in your stack?
thickness of dollar bill=(63E-6)*1.5m
= .08m/(1.5*63E-6)m= you do it. I get less than 900
