Ridiculously, there's no straightforward way to do this.  The best way
is probably to convert the cub file to a 4D file with vb2tes and then
use sumrfx.  i.e.,

vb2tes my.cub my.tes
sumrfx -m mask my.tes

sumrfx is a horrible kludge written to provide some semi-random
summary stats on 4D files, it has very limited usefulness but is
helpful here.
