A museum Battlestar does not begin fully supplied

Galactica's size does not answer the supply question raised by the story's opening conditions. The ship is halfway through decommissioning and conversion into a museum, so its enormous internal volume should not be assumed to be packed with operational supplies. The first episode's shortage premise is consistent with stripped or empty spaces rather than a fully stocked warship. Physical size does not create endurance without stores, crew, and an active support system.
