It's not a bad figure, the city is likely far more vertical than any modern city where the vast majority of all buildings are 1-3 stories. If the city has multiple street levels, you could have 5 story buildings stacked on each other until the city starts to feel underpopulated instead of overcrowded. With the ability to build down into the water, that's more practical than it might first seem.

But its a cybercity! Overcrowding is a feature!
