Explain why it is important to understand the base for a number as well as the value.

How does expressing this number in scientific notation change the way you understand.

How many bucketloads would it take to bucket out the world's oceans? Write your answer in scientific notation.

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
