Forum rules
Dear convert-me.com forum visitors,
Our forum has been available for many years. In September 2014 we decided to switch it to read-only mode. Month after month we saw less posts with questions and answers from real people and more spam posts. We were spending more and more resources cleaning the spam until there were less them 1 legitimate message per 100 spam posts. Then we decided it's time to stop.
All the posts in the forum will be available and searchable. We understand there are a lot of useful information and we aren't going to remove anything. As for the new questions, you can always ask them on convert-me.com FaceBook page
Thank you for being with us and sorry for any inconveniences this could caused.

I am doing aschool class. Making imaginary landforms. The giant baby bottl is one. I also need to know how large a plexiglass piggybank would have to be to contain 905,000 3mm colored beads. your help was excellent would appreciate more. I will look at the Wkipedia site, math however is not my strong suit.

Please note I amended my other answer based on "random close packing" which probably describes your case more accurately.
Calculate volume of the beads
Vb = n*(pi/6)*d³ = 0.01279 m³ = 12.79 L
Assuming random close packing factor of 64%, you need about 12.79 L/0.64 = 20 L.
