It means the true volume could be anything between 1,779.55 cubic meters and 2,036.45 cubic meters. This " +/- " form represents the uncertainty of determining volumes using photogrammetry with limited accuracy.
BUT THERE IS MUCH DIFFERENCE.
1779 ,1908 & 2036 CUBIC METERS.
WE NEED ACCURATE. WHAT IS TO BE DONE.

I am not an expert but it seems your GSD may be too large. I am getting uncertainties of about +/-1% using a 2cm GSD. Whereas you are getting +/-6.5%.
A 1% tolerance is acceptable for my circumstance but may not be for you.
