not my strength. A 3600ppi scan from one of my negs, on a 16-bit

film scanner, works out to be about 33mb and has dimensions of more
than
5600 x 3600. If I were to scan full frame, showing some borders,
I'd be at
about 35mb. Don't know how you're getting such a small scan.
The calculation used 3000ppi rather than the 3600 mentioned
beforehand (see below).

The final image is 4500x3000 pixels for a leica negative
(most of the time I am shooting on 35mm film). The math is
4500x3000x2/1024/1024 = 25,7 Mb (2 bytes per pixel, Kb and Kb are
1024
bytes or kbytes).
