**Approximately 74,700 dollar bills will fit into a medium-sized suitcase that measures 11 inches long, 18 inches wide and 26 inches tall.** When multiplied together, the suitcase has a volume of 5,148 inches cubed.

To calculate how many dollar bills fit into suitcases with different volumes, basic algebra is required. A stack of 100 standard bills measures 6.14 inches long, 2.61 inches wide and .43 inches tall. When multiplied together, its volume is 6.89 inches cubed. At this point, divide the volume of the suitcase by the volume of a stack of bills. To use the previously given example, 6.89 fits into 5,148 (the volume in cubic inches of the medium-sized suitcase) about 747 times. However, 6.89 represents a stack of 100 bills. Therefore, multiply 747 by 100, which provides an answer of 74,700.
