Here are the numbers:
a 1 dollar bill is .66294 cm thick
so if you have 1 trillion of them that would be:
662,940,000,000 cm
or
21,749,999,999.979294 ft
which in turn is
4,119,318.181 mi.
OR
4,119,318 mi. and 319.9 yd
Now that is if I did the math correct... Just a little useless info to fill up your gray matter...
as a side note the surface area of a dollar bill is 16.0254 in^2 anyone want to do the math as to the sqft of 1 trillion dollar bills laid end to end a side to side... wow...
