According to my simplistic math using standard 10x12x15 inch boxes of pages where each box has 5000 sheets, it's about a 15x15x15 meter cube. 15 meters is approximately a 5 story building. If it's 16lb paper, then about 3,828 metric tonnes. Obviously the weight of the paper is a huge factor here. Another way of looking at it: if there are 260 days in a year (not counting weekends), then over a period of, say, 10 years, it amounts to 1.47 metric ton per day.
