but why? this is a radius of a bottle and is diagonal of a square..

Weirdly, 1 random test randomly fails for my solution...

Such a sweet description and an interesting task for the beginners, I really liked this kata ^^

Python: Random tests: 616 of 616 passed. Fixed tests 2 of 10 passed. How stupid is this 🤯 ?

The description is not wrong. You misunderstood the problem and likely just guessed your way into the correct formula.

The description is wrong: "The brick's length and width are equal, forming a square" ------ The length and width are NOT equal in the examples. It's NOT an square. Please, fix that.

The task itself is pretty interesting, but it doesn't seem to be a 8 kyu task, it should be ranked higher. Or some geometry formulas must be given in the task description.

The tests have a problem! agreed

Good challenge to have fun with.

JS && TS:

Initial solution setup should provide the method and constructor signatures.

The kata expects the function to return a string of "Invalid input" when the input is invalid, not terminating the script entirely.

I code on PHP, i just don't understanding why it fails in logic section, it doesn't even saying why it fails it just saying "Invalid input" so i don't even getting where it fails, when i run every unit test in my ide everything work fine but when i attempt it fails for some reason, so plz take a look.

The problem is poorly written, it needs the grammar checked so that it can be read easily.

No, it doesn't. And you have to calculate the volume of a cuboid. Next time, write in english, please.
