(e) How high would a stack of quarters worth 1 million dollars be? Answer in meters (M)

Answer 1

For D, how many pennies are in a million dollars? Multiply that by 1.55 mm, then convert to meters.
For E, do the same but with quarters! :D

Answer 4

kymber, thought thats what I did but my answer is not correct.

Answer 5

100,000,000 pennies in a million dollars multiplied by 1.55 is 155,000,000 millimeters then converted to meters is 155,000 meters. That's what I got, what did you get?

Answer 6

15500

Answer 7

I think it's 155,000 :P

Answer 8

got 175000 but thats wrong for part e

Answer 9

ah so for d.) if we have a stack of pennies worth 1million dollar we'll have a stack of 100 million dollar then multiply that to 1.55 mm to get 155000000 millimeters which is just 155000 meters exactly like kymber's answer
e.) so if there are 4 quarters in one dollar we'll have a stack of 4 million quarters then multiply that to 1.75 mm to get 7000000 mm which is 7000 meters

Answer 10
