You would likely go into scientific notation with both A and C. I'm not even sure that A wouldn't go into overflow, but if it doesn't the number would be meaninglessly large.
Most NBA courts are measured in Feet (or yards) or meters. High school and college courts are measure the same way. Very few references measure the height but one said that a high school Gym has to be at least 16 feet high. So given the space for spectators, you're talking a lot of m^3 or yd^3
