Final answer:
A stack of 4 trillion one dollar bills would be approximately 400,000,000 meters tall.
Step-by-step explanation:
To determine the height of a stack of 4 trillion one dollar bills, we need to find the total thickness of the bills and convert it to meters. Given that a one dollar bill is 0.0001 meters thick, we can calculate the height by multiplying the thickness by the number of bills in the stack:
Height = 0.0001 meters/bill * 4 trillion bills
Converting trillion to 10^12, we have:
Height = 0.0001 meters/bill * 4 * 10^12 bills
Using scientific notation, we rewrite the expression as:
Height = 4 * 10^12 * 0.0001 meters
Performing the multiplication, we get:
Height = 4 * 10^12 * 0.0001 meters = 4 * 10^8 meters
Therefore, a stack of 4 trillion one dollar bills would be approximately 400,000,000 meters tall.
