cubical

The word 'cubical' has a geometric lineage tracing back to the Greek word 'kubos', meaning a six-sided die or a solid block. This term was adopted into Latin as 'cubus'. In English, the root 'cub-' was combined with the adjectival suffix '-ic', borrowed from Greek via Latin, to form 'cubic', meaning "of or relating to a cube in shape or volume". The additional layer of the Latin suffix '-al' was later appended, creating a double adjectival form 'cubical', which essentially reinforces the descriptive meaning. Thus, the modern term logically builds from the ancient concept of a cube, through successive linguistic layers, to describe anything having the form or properties of a cube.
