My partner is a DIY man (he likes sawing up pieces of wood and then nailing them to my walls and telling me that it's a bookcase) so I hear a lot of 3x4 and 4X6 so I guessed it was something similar.
I was also guessing it was 3x3, but I didn't want to make any assumptions. But I still don't entirely understand what it means - is it a small room, 3m x 3m? What is this a commercial for?
The commercial was for furniture or smth like that. Like you have a small room (3mx3m) and what can you put in it I wonder why Dragomir needs translation for that but nevermind.
