Not quite. If my calculations from Google Earth combined with an aerial photo are correct, the show building should have a footprint of about 40,000 sq ft, assuming it's a two story you'd get about 80,000 sq ft of floor space. Although all of Battle Escape show building is the height of a two story structure, the queue will just have a super tall ceiling. Therefore, the square footage of Battle Escape is around 120,000 sq ft.
Here's the outline I drew combined with the aerial I drew it from (sorry about resolution, had to shrink to get under 2 MB):
