That depends on the volume and unit of the currency. If we only use U.S. one dollar bills, then according to http://wiki.answers.com/Q/What_is_the_volume_of_a_dollar_billhttp://wiki.answers.com/Q/What_is_the_volume_of_a_dollar_bil, a dollar bill has a volume of about 0.06890922 cubic inches. A trillion bills then would be 68909220000 cubic inches. If the pile is six feet - or 72 inches - deep, then the area will be 68909220000 / 72 square inches. There are 6272640 square inches in an acre, so the total number of acres would be:
68909220000 / (72 * 6272640)
= 68909220000 / (451630080)
= 152.578898199
So a six-foot deep pile of U.S. one dollar bills - assuming they're perfectly packed with no unused space - would require about 152.58 acres to reach a trillion dollars.
