Hi everyone!
Who knows how many units of the cube have been sold in the world since its invention? Do you know any approximation of that number?
I've searched the web and I've found 350 millions, but I think this number is obsolete.
Do you know any updated reference?
Thank you in advance.
P.D.: This is my first post. To any administrator, feel free to move it or delete it if it's not correct or appropiate for this topic. I've searched for the question and I think it's not already answered.
