USA TODAY Math TODAY: The New Color of Money 2
Enter the number of inches high that the stack of $20
bills would be and highlight in for inches on the
screen. Then press b.
Notice that the number of inches is listed in scientific
notation with the units shown. Highlight the units of
measure to which inches are being converted—mi
for miles. Press b again.
The height of the stack is shown in scientific notation
as miles. In this case, since the original data is
accurate to only 2 significant digits, this result should
also be expressed to 2 significant digits of
accuracy—3.5 x 10
2
(or 350) miles.
The solution can be exported outside the App to the
handheld home screen by pressing q to select
the EXPT option from the bottom of the screen.
In Step 4, the number of cubic inches in 1 cubic foot
can be found easily. Then exit the program to find
the volume of all the $20 bills in cubic inches before
returning to the converter to find the volume in cubic
feet.
