Caves are recorded by passage length totals, not area, except perhaps when analysing their local geographical context. The World's longest is the Mammoth Cave - Flint Ridge Cave system.
Mammoth cave in Kentucky is big in fact the biggest cave in the world! (By total surveyed length.)
Its sheer length - the combined Mammoth Cave / Flint Ridge cave system holds well over 350 miles of surveyed passages; the world's longest known cave. Apart from thatalthough the system is a normal karst cave(in limestone) so holds examples of typical cave passage morphologies, calcite formations etc, it is as individual as any cave - one of the values that make caves so fascinating!
Taking "largest" to mean longest... Not easy to establish - different sources quote different lengths but the most extensive is the Flint Ridge - Mammoth Cave system, in Kentucky,with over 350 miles of surveyed passages. Caves over 100 miles long are unusual; one of this magnitude rare.This length is notof a single passage but a complex network.
