How do I determine the Surface Area Units used in the Polygon Volume tool?

I am trying to calculate the surface area inside of a polygon from a TIN which I have generated from a DEM. The Data Frame Projection is WGS 1984 UTM Zone 37S, as is the polygon. The TIN generated from the DEM is in WGS 1984. When I run the "Polygon Volume" tool I end up with the value of 96.248, but I'm not sure what units the SArea is being reported back in.


The UTM coordinates are recorded in Meters, but I know that the surface area is not being reported in meters, as 96 is far too small.


When I tried to project the TIN into WGS 1984 UTM Zone 37S, it no longer matches the location of the polygon.


What am I missing?
