    Design a function that calculates the storage capacity of a cubic medical supply unit in the ICU, where the unit's internal dimensions are equal on all sides. The storage volume calculation will help determine the maximum quantity of critical care supplies that can be stored and assist in maintaining optimal inventory levels for patient care.
