When is zero squared a cube?

[i]I know that those of you in the UK should be able to get this puzzle. I am not too sure about those of you in other countries.[/i]

I've just had a PM from Steve Fowkes, who not only has the right answer, but has also informed me that American puzzle solvers should be able to get this too

Surely more than one person is going to solve this?

I'm confused since zero squared IS a cube!
Zero squared is zero and zero is also the cube of zero.

When ISN'T zero squared a cube?

Does this have to do with freezing water?

Nothing to do with frozen water, however you have the right shape Jonathan.

Stan, You are absolutely correct. There is a really neat solution to this, though. It will help if you write the sum out as an equation

Sum? Product, you mean?

Confused,

When z*e*r*o = n^(3/2) where n is a positive integer?

Yeah, ok: product.

As for the z*e*r*o etc: no.

Zero squared, could be written as 0^2. How else could it be written?

00, 0*0, 0x0, 0.0 (with the dot slightly higher up) or of course 0 with a small 2 in the upper right corner. Hmmm, so does that resemble a logo for some UK company which has something to do with cube shaped objects? Trying to get my head around why it should work better for brits and americans. :)

Ah, found that a company named "oxo" makes stock cubes. http://www.oxo.co.uk/

So the answer is "When you interpret '0' as the letter 'o' and the multiplication sign as the letter 'x'."

You have stumbled on the right answer, Thomas. One of those you mentioned is indeed a brand name. Feel free to do an internet search

X post... You have the right answer!

OXO is a brand of gravy stock, commonly known (in the UK and US) as an Oxo cube
