you are wrong

pyramid and prism is two different things

?

Duplicate messages... I mean issue

But isn't it a good thing that you have to think for a while before solving a task?

only this may not help

What language? Unless it is something new there are many 100s of successful solutions, so problem is likely in your code. Certainly, don't do any intermediate roundings...

which units need to be rounded and in which direction

Kata already says "Round down to the nearest minute."

"The game starts at level 0. The level increases every ten lines you clear."

It's pretty self explanatory..

IMHO the unit of measure should be the side of covers.

In bit-wise operations, we start off from the end (right) of bits, not from the start (left). Also, it is not moving the bits, but flipping the bits.

I'm not sure how to do it without more confusing. Actually, it doesn't matter which system to use. And 12.375 looks better than 30,43

Because standards were not established so firmly back then until recent 3-4 years. The "administration force" now has been growing but it's all a self-voluntarily action from users. On top of that, there are almost 9000 approved katas and 2000++ betas, plus tons of translations and languages to maintain, soo there is no specific T.O.C on any updates or changes.

You can always provide a suggestion in kata discourse or create a fork of the kata with updated description. I believe me or any other reviewers who come across will gladly give you feedback and approve it ^^
