I want to know the answer to the following question:
About how many people live in a square kilometer in Gonggabu VDC?
All the background I'm provided with is that "The urban area of the Kathmandu valley is split among three different districts (collections of local government units within a zone) which extend very little beyond the valley fringe, except towards the southern ranges, which have comparatively small population.". Is that enough to answer the question?
