J.P. Guilford, the proponent of the Structure of Intellect Model of intelligence, classified intellectual abilities into how many dimensions in his model, and what was the total number of independent factors in the original model presented by him?

The Structure of Intellect Model proposed by J.P. Guilford posits that intelligence is a complex compilation of three independent dimensions: Contents, Operations, and Products. Originally, this model conceptualized 4 (Contents) × 5 (Operations) × 6 (Products) = 120 independent intellectual factors, which was later revised and expanded to 150 and then 180.
