The Bank Heist Big Bills After recently watching Kill Bill again, the scene of a million dollars in a suitcase along with a black mamba snake sparked curiosity to figure if this could be done. It is possible to carry around a million in cash? What type of currency would be used and would it technically all fit?
The U.S Department of Treasury had several things listed on their site (treasury.gov) with information on currency. Before diving into the hypothesis, learn some history on the larger bills.

Dec 18, 1934 the largest denomination of currency was printed, being called the “100,000 series”, with President Wilson gracing the front. This bill was only used for official transactions between Federal Reserve Banks, used from 12/18/1934 to 9/09/1935 and was never released to the public. In July of 1969 (treasury.gov) the Federal Board decided to stop printing and distributing $500, $1,000, $5,000, and $10,000 dollar bills. They had only been used for bank transfer payments only, and with the improved technology the larger bills were not needed anymore. Some of these bills remain, but through private collectors. Learning this, a person could not just speculate they would receive and carry their million using five or ten-thousand dollar bills.
The Heist Itself The dimensions of a standard bill according to enchantedlearning.com/edu are as follows; 6.14 x 2.61 x 0.0043 and weighing 1 gram each. Planning this heist to carry out a million in cash, there were several things to do to be prepared for this. First, the briefcase is the biggest necessity and not all are created equal. But in homage to the heist films genre, a standard attaché briefcase would be required. Dimensions of this briefcase are 18.5 x 13.25 x 4.5 (briefcase-usa.com) and fairly decent with only a $100 price tag. Use one-hundred 100$ dollar bills; stack them up and, each stack being respectfully ten-thousand dollars. Successfully laying seven $10,000 stacks face side up, side by side along the bottom of the briefcase would fit best. Repeat this with another row behind the first, for a total of fourteen, each layer representing $140,000. Add another layer of fourteen on top of the first, and continuing to do this until there is seven stacks high each. The briefcase is now at a grand total of $980,000. Ensuring the briefcase could hold in the amount, measuring again might be needed. Each $100 bill is 0.0043 in height and using a hundred per stack to equal $10,000; 0.0043x100=0.43 in height, then with 7 layers 0.43 x7= 3.01 inches total.
Finishing details Having almost near the required grand total, and only having used 3 inches in height of the 4.5 inch deep briefcase, safely adding another stacks and the height would be still safe at 3.44 inches. Success! The task was accomplished easily putting a million dollars in cash into the attaché briefcase .Only question remaining is, how much is this going to weight and can it be carried this one person?

Heavy weight US currency is made of 25% linen and 75% cotton, according to enchantedlearning.com/edu. Each bill weights only 1gram, and there is ten thousand, $100 dollar bills total. 10,000x1gm= 10,000 grams and converts to 10 kilograms using the metric system. 10 kg x 2.2 lbs= 22. So this briefcase full of money would only weigh around 22 pounds give it or take, depending on if that poisonous Black Mamba snake was tossed in there as well?
