Has anyone solved it?
I'm sorry, but it's about length, not height.

Here are some more challenging problems :)
#26
There are ten numbered hats on the table. Each hat contains ten gold coins. One of the hats contains
fake coins. A genuine coin weighs 10 grams, while a fake one weighs only 9 grams. You have scales with a gram scale to help you. How can you determine
which hat contains the fake coins using the scales for only one weighing?

The sultan had 12 viziers. He learned that some of the viziers had unfaithful wives. He decided to punish them. He did the following:
each vizier and his wife were placed in completely isolated rooms, and they were told that they would remain locked up until all
unfaithful wives were killed by their husbands. Every morning, a servant checks each room to see if this condition has been met. As soon as it is determined that all unfaithful wives are dead, everyone is released. On the 3rd day, everyone was released, and all faithful wives
remained alive. How did the viziers figure it out?
Clarification. All the viziers are very smart, and there are plenty of rumors in the palace, so each vizier knows whether each other vizier's wife is faithful or unfaithful, but knows nothing about his own. There is no exchange of information while they are locked up.
#28
You are in a labyrinth. You wandered for a long time and finally, exhausted, found yourself in a room with two doors: one leads to freedom, the other to
certain death. There is a guard at each door. One always lies, and the other always tells the truth. You don't know which door
is which and who is who. What one question should you ask to determine the correct door?
#29
Two bandits, after a successful robbery, are dividing the loot - gold sand. They have no scales or other devices. They don't trust each other. How can they divide the loot between the two bandits so that neither of them feels cheated?
#30 What is equal to
(K·A·R·L·S·O·N)/(V·A·R·E·N·Y·E)
Each letter is a digit (from 0 to 9). Identical letters correspond to identical digits, and different letters correspond to different digits.
The answer turns out to be a specific number :)
