Think of a financial model as a structured, multi-dimensional representation of inputs, calculations, and outputs that you can analyze across different dimensions like time, scenario, or product. In analytics, that kind of structure is described as a data cube. The term cube conveys the idea of organizing data across multiple axes so you can slice, dice, and aggregate results to see how changes in assumptions affect outcomes. That makes cube the best fit for describing a financial model among the given options. The other shapes don’t carry this analytical, multi-dimensional meaning and aren’t used to describe how financial data is modeled and analyzed.
