    Calculate the air volume capacity of a medical isolation unit, which is designed as a perfect cube, to determine proper ventilation requirements for infection control when given the length of any wall in the isolation chamber. The isolation unit's air volume is essential for maintaining appropriate air exchange rates and preventing the spread of airborne pathogens.
