What is the minimum spatial IQ needed to solve the rubik's cube?
I don't think it's a matter of IQ, really. Here's why: The Rubik's cube can be solved easily following a simple algorithm. Anyone can follow this step-by-step process mindlessly and solve a Rubik's cube. Remembering the algorithm is a different thing altogether, maybe that depends on a person's IQ (does memory depend on IQ?) There are many bots that can solve the Rubik's cube in a matter of seconds, just following this algorithm. So, it actually doesn't need much IQ I guess, but considering that the algorithm generally starts from the step after one side (usually black/white/yellow) is completed, a person should have enough IQ to be able to solve one face of the cube and remember the steps, so I am guessing that the IQ measure would be around the room temperature in Celsius scale!
