yeah, this frustrated me for a bit because the solution I wrote seemed to work fine in the console but would not work in codewars. I guess I should have paid more attention and ran the equations as they were written with the extra space!

JavaScript as well

Closing then.

Is it ok now?

And for that, you would need rim_radius. No, sorry, I can't see the ambuigity. You're thinking about a different problem. Maybe mentioning the brick is the largest you can fit inside the bottle would help, yes, it's like that in the picture, but in words would be better. But, if you think a minute about it, your function can't return inifinite values. The examples and sample tests show that.

It does say:

The brick cannot fit inside the rim.

What's the ambiguity?
