Want to give this a shot?

From the picture you may be able to see that it is raining heavily. Sitting in my balcony, I can see the rain drops hit the parking lot surface in the light that is reflected there.

Here is a question that flashed thru my mind. How many raindrops does the earth get? Millions? Billions? Trillions?

To get started, let’s say it rained in Alpharetta (say 25 square miles) this morning for about 4 hours. How many raindrops did we get?

First take a guess. Just guess how many zeroes (or digits) will be there in that number.

Now, try to do the math. Make whatever assumptions you need to. (And they will differ from person to person). What number do you get? How many digits?

How close were you?
