1 Trillion dollars

1 dollars bills    1.1 million tons

                       22 billion pounds

100 dollar bills  11 thousands tons 

                      2.2 million pounds

If you stacked a trillion $1 bills (US) on top of each other, you'd form a stack that reached a quarter of the way to the moon --the stack would be nearly 70,000 miles high or three times  around the equator

 A dollar bill's dimensions are about 2.6" x 6.1" x .0043"

$253 million to cover a one-mile by one-mile square.

So $1 trillion in one-dollar bills would cover an area of about 3,857 square miles  

$1trillion in one-dollar bills (if packed perfectly) would fill a volume of about            40 million cubic feet

Minneapolis sports stadium Metrodome Interior volume is 60 million cubic feet

will fill the Metrodome 2/3 full
