The U.S. federal debt, at the time of the writing of this exercise, was $20 trillion. One way to get a sense of the enormousness of that number is to imagine how much space 20 trillion one-dollar bills would occupy. What expression represents this space? volume of a dollar x 20 volume of a dollar x 20,000 volume of a dollar x 20,000,000 volume of a dollar x 20,000,000,000 volume of a dollar x 20,000,000,000,000 OOO OO Determine the space (in cubic feet). (Assume a dollar bill is 2.61 inches wide, 6.14 inches long and 0.0043 inches thick. Round your answer to the nearest whole number.) ft³ Recommend a denomination that would enable a semitrailer to haul that much money. (Assume a semitrailer can hold 163,000,000 bills.) $500 $1,000 $10,000 $50,000 $1,000,000 OOO OO
