I understand that football stadium play area is standard, but how do you measure height?
Is it a foul to kick the ball too high in the air? The play area, I assume isn't limited vertically.
It says "volume of twelve stadiums" so maybe by treating an entire stadium as a giant bowl up to the top of the seating? But who knows what stadium is the reference stadium - that's not a consistent thing like the size of a football field.
