how do your eyes see time?
anything with more than 3 unique, independent variables can be represented with more than 3 dimensions. that's all the formalism is. consider minor perturbances in the em field of the earth as we traverse about the galaxy and with it thru intergalactic regions. our orientation is constantly changing causing measurable field disturbances, but with only considering 3 changing variables we can't precisely model the change.
the idea of a 4d cube is not divorced from reality, u can see the multiplicitous nature of a cube in the op. many shapes with different sides and angles and relationships all give the same volume when considered together with their duals. we simply use additional dimensions to model additional Flux, and formalisms, like the hypercube come from academic investigation of the n dimensional space of itself, and what relationships quantities have with themselves in some set field of operations
