How many pennies make 1 Googol dollars?

Answer 1

You could say, 100 Googol pennies make a Googol dollars, and that's right.

However, Googol is not the official name of the number having a 1 followed by one hundred zeros. Actually the official name of 1 Googol is 10 Duotigentillion.

And 10 Duotigentillion dollars would be (100 x 10) Duotigentillion pennies. Since (10 x 100) is 1000, we need to use the name for the next big number. Just like 1000 Thousand is 1 Million, and 1000 Million is 1 Billion, 1000 Duotrigentillion is 1 Trestrigintillion.

So 1 Googol dollars is made from 1 Trestrigintillion pennies, to use the proper names for numbers.
