What size breaf case will hold one million dollars?

The size of a briefcase required to hold one million dollars depends on the denomination of the bills. For example, if using $100 bills, one million dollars would weigh about 22 pounds and fit into a briefcase of approximately 2.5 cubic feet. However, if using $1 bills, it would take up significantly more space, requiring a much larger briefcase or multiple cases, as it would weigh around 2200 pounds and take up roughly 40 cubic feet.
