A 1 foot tall stack holds 1,647,360 bits of data if all 80 columns are used. If only 72 columns are used for data then it’s 1,482,624 bits of data and the remaining columns can be used to number each card so they can be put back in order after the stack is dropped.
How about feet of IBM punch cards?
