Oh, you mean useless speculation. I would love to see the details of this "calculation", just for its comedic value.
=========================
Assuming
all $100 bills:
| Item | Estimate |
|---|
| Cash amount | $3,000,000,000 |
| Bills needed at $100 each | 30,000,000 bills |
| Weight of bills | 30,000 kg / 66,139 lb |
| Raw note volume | about 1,196 ft³ |
| Practical 747 PMC pallet load limit | about 6,800 kg gross |
| Pallets by weight | 5 pallets |
The weight drives the answer. U.S. notes weigh about
1 gram each, regardless of denomination, according to the Bureau of Engraving and Printing. So 30 million $100 bills weigh about
30 metric tons.
A standard 747-compatible
PMC/P6P air pallet is roughly
96 × 125 inches and has a main-deck max gross weight around
6,800 kg, so $3 billion in $100 bills divides into
5 pallets at about
$600 million per pallet, or roughly
6,000 kg / 13,228 lb of notes per pallet.
A 747-8F could easily carry that: Boeing lists maximum revenue payload around
137.8 metric tons, far above the roughly
30–31 tons including pallet tare/packaging.
==================================
| 30 pallets of $100 bills | Amount |
|---|
| Value per pallet | $600 million |
| Cash weight per pallet | 6,000 kg / 13,228 lb |
| Total value | $18 billion |
| Total cash weight | 180,000 kg / 396,832 lb |
| Total cash weight in U.S. tons | 198.4 short tons |
| Total cash weight in metric tons | 180 metric tons |
So
30 pallets would contain about $18 billion and weigh about 180 metric tons in cash alone.
That would be
too heavy for a 747 freighter if all 30 pallets were filled that way. A 747-8F max payload is roughly
138 metric tons, so 30 fully loaded cash pallets would exceed payload capacity before adding pallet tare, packaging, guards, containers, or fuel-range penalties.
