The thickness of a $1 bill is 0.11 mm. If you have a stack of $1 bills 450 m tall, how much money do you have?

You will have 4.5 million dollar

Explanation:

The thickness of a $1 bill is 0.11 mm

So we have

1 $ = 0.1 mm

0.1 mm = 1 $

0.0001 m = 1 $

1 m = 10000 $

450 m = 450 x 10000 = 4500000 $

So you will have 4.5 million dollar

4090909

Explanation:

Thickness of one bill = 0.11 mm

Total thickness = 450 m

No of $1 bills = total thickness / thickness of one bill

No of $1 bills = 450 / 0.11 * 10^-3

= 4090909
