How many gallons of milk do cows give off in one day in Asia?

1.  Background Story:

How many gallons of milk are milked from cows every day in Asia?

I chose this because it followed all the rules. It involves a very large number. There is a place and a certain time. This cannot be googled and it sounds like something fun to do.

2.  Ask Yourself This:  

How many cows are in Asia?

How many gallons of milk does a cow in Asia make?

How many cows come to or leave Asia?

3.  Helpful Hints 

a.  

There are 390 million cows in Asia

The average amount of gallons that a cow in Asia makes per day is 4-5 gallons.

 Cows do go in and out of Asia      

b.

I do not have the exact amount of gallons that a cow makes in Asia but I do have it probably in the U.S. but cows in Asia don't get fed and cared for anywhere near as well so they make less milk. 

4.  Construct a Formula:

What I would have to do is use the info I have. I know that there are 390 million cows in Asia and each cow can make an average of 4-5 gallons. I would have to multiply 5 gallons by 390 million cows in Asia.  I estimated that Asian cows would make around 5 gallons.

5.  Messy Math: 

        

   My problem was the 390 million cows multiplied by the five gallons of milk that a cows makes in Asia.

  

6.  Answer:  

The answer is 3.9x10^7 gallons of milk     

     The population of China is 1.3608x10^9 people
