SGA size has nothing to do here.
datafile size is what that matters.
To b accurate you can
sum of size all datafiles (allocated)
or
sum of actual space within the datafiles ( utilized).

Yes. That is the allocated size.
You may also want to consider the actual database size (you allocate 1gb datafile. But the database may be using only 100m).
