By querying the SAS dictionary, you could get a approximate figure.
If the table is compressed, or has index, it's getting a bit more complex.
If you have tables in BASE engine you could read the OS information, pipe it back to (but this wouldn't be SQL).

Sorry, forget sample code:
create table tab as
select libname, memname, nobs, obslen, nobs*obslen as Bytes
