How many lacrosse balls will it take to fill the Atlantic Ocean

1.  Background Story: 

 Have you ever wondered how big a lacrosse ball is? My question is how many lacrosse balls will it take to fit in the Atlantic Ocean. I chose this question because I really like lacrosse and it seems like it will be cool to see a comparison how big the Atlantic Ocean is. 

2.  Ask Yourself This: .

What's the volume of the Atlantic Ocean?

How many cubed inches will a lacrosse ball take up?

How will I fill the space in between balls because they are round they will not stack up. 

3.  Helpful Hints:  

.

3 x 10^20L that's how many liters of water. About 320 million cubic kilometers. Or 80 million cubic miles. 

3.20000000

3.2x10^8

.

a lacrosse ball is about 2’’ around and 2’’ tall and when they stack up, there will be a space in between the balls that will not be filled. It will not be filled because when you stack up lacrosse balls, they are round so there is space in between.

4.  Construct a Formula: .

Diameter .times half mile times those balls acrosse times miles up 

You multiply by half mile because each ball is two inches so if you multiply by half mile you'd get a mile long line of lacrosse balls. 

What I will do in order to find out how many lacrosse balls will fit into the Atlantic Ocean is find out how many miles cubed the Atlantic Ocean is, then I'll find out how many lacrosse balls will fit into one cubic mile. Then multiply that number by how many cubic miles there is in the Atlantic Ocean. Which will get you to the answer. 

5.  Messy Math: .

2"x2640'x2640'x8x10^6m=1115136x10^8 lacrosse balls. 

(Need to include all your units here - scientific notation?)

6.  Answer:  

There is about 1115136x10^8 lacrosse balls. And that's not including all the space in between the balls that's not filled up. Imagine how many it would be if you filled the space between balls
