How big is the Makassar Strait?
About 184,106 km² of water inside its Natural Earth outline, counted from the grid cells that are below sea level.
How much of the Makassar Strait would be land if sea level dropped?
With the sea 10 m lower, about 9,318 km² (5.1%) of its water would be land. At 6,000 m lower, 100% would be. This is a simple bathtub model that lowers the sea evenly everywhere.
