If the human body is roughly three cubic feet, and the stay-puft marshmallow man is roughly 30 times the size of a human, i.e. about 150 feet tall, then he is 30*30*30*3 cubic feet, or 81,000 cubic feet. Call it 100,000 cubic feet since he's chubbier than an average human. If you can eat one cubic foot of marshmallow per day, that would be 100,000 days, or 275 years.
