Is it reasonable for a hotel room to be ten meters long?

The length of the hotel room is 10 meter. According to relevant data, in the design of conventional hotel rooms, the column spacing between rooms is generally 3.7-5m, and the column spacing between rooms is generally 7 7- 10/0m, and the construction area including toilets is 30-50m, of which the net area does not include 20-40m2 toilets and 5-8m toilets. When the room size is about 3.9× 7.5m, the ratio of building cost to room function is extremely reasonable, so the hotel room length is10m.
