How high is the IQ of a person who can independently spell out the six sides of the Rubik's Cube?

Rubik's cube, also known as Rubik's cube. It was invented by Professor Erno rubik of Budapest Institute of Architecture in 1974. He didn't invent the Rubik's Cube for production and entertainment. As a professor of architecture and sculpture, he made the first prototype of the Rubik's Cube to help students understand the composition and structure of the spatial cube and exercise their spatial thinking ability and memory. For this simple purpose, he finished his first work, but you know, making a Rubik's cube is not simple. It is not only a mechanical problem, but also involves wooden shafts, seats and tenons. After a long time of hard work, I still overcame the above problems-1974 The world's first Rubik's cube came out! When he held the Rubik's Cube in his hand, he accidentally turned it over several times, only to find that the original neat Rubik's Cube was actually difficult to recover, so he realized that this new invention would be difficult.

It took rubik a week to find the pattern. If you are completely independent, you can spell well and have a high IQ. As for the book "50 seconds for mentally retarded people", everyone who can play knows that the person who wrote this book must be mentally retarded.
