How many Maltesers would fill a bathtub?

Maltesers are small chocolate balls filled with honeycomb (Wikipedia for anyone not in the UK who may not know them by the same name)

If I was to get a bathtub full of them, about how many packets or boxes of them would I need?!

H2G2 has a count of how many Maltesers are in a bag or box, but I've no idea how many boxes would fill a bath.

Are you filling the bathtub with boxes or bags or with individual chocolate balls?
When you fill the bathtub, do you use a loose packing, a random packing, or the densest possible packing without crushing?
Or do  you allow crushing of the balls or boxed in order to squeeze in as much as possible?
Do you want the loosest possible arrangement of boxes such that no other box can be added without moving an already added box?   Do you want the loosest possible rigid packing?

Here are some random close packing densities for spheres

Individual balls - ie not in any packaging

I'm not sure of the difference between loose packing or random packing.  Whichever it'd be if I emptied x boxes of individual balls into a bath without doing anything special to squash them in.

Or do  you allow crushing of the balls or boxed in order to squeeze in as much as possible?
No, no crushing.  If a bathtub is about 60cm tall and a Malteser is about 15mm in diameter, that's about 40 Maltesers high: I think a Malteser would support the weight of 40 others without crushing.

Do you want the loosest possible arrangement of boxes such that no other box can be added without moving an already added box?   Do you want the loosest possible rigid packing?
Loose is fine - using the Wikipedia page's example of shaking a tub of grain to compact the grain - I'm not worried about shaking the bathtub.
A 60 cm deep tub is larger than a "standard" bathtub.
What are the other dimensions of the tub we are talking about?
Go with whatever you think a standard tub is - I guessed at 60cm only to say that I didn't think you needed to worry about crushing the bottom Malteser with the weight of however many go above it.
It would depend on the size and style of the bathtub. I'd guess in a normal bathtub of approximately 1700x700x450mm in size and assuming each malteaser is 10mm in diameter you'd need over 500,000 individual sweets
