How many regular size marbles can you fit inside a standard size bath tub?

Ajromero – Do we look like Engineer’s??

Speaking for myself I’m definitely not but I’ll take a shot at it!
Lets put your “Standard” size bathtub at 60*30″ so that will give us approximately 1800Sq.Inches. right?

Now lets say that your marble is your standard 9/16″ marble which is used for chinese checkers.

I think from here we need to do 1800 sq.Inches divided by 9/16″ or .5625 so it would be 1800/.5625 and would equal 3200 Marbles.

let me know if this sounds right to you.
