Now that's a great answer. I like how you showed your work.
Someone should write a math textbook called "Bible Math". Problems to solve could include:
-How much it would cost to rebuild Noah's Ark
-How many lives could be saved if the water turned to blood in Exodus was used for blood transfustions
-How much it would cost to build the walls of Heaven in Revelation.
That number is too small. If God turned Lot's Wife into a statue of salt, I expect that statue to be 100% pure salt. An average human female weighs 77,564 grams. That's enough for 686 salt shakers (if they can hold 113 grams).
