used segment space in bytes

hi guys!
 

what would be the easiest way to compute the space
in bytes used by a segment?
it is rather easy to determine the # of used blocks
by a specific segment by looking at the dba_extents
for example. but how many blocks have been really used
in one of those extents. i guess i would be able
to compute the free blocks by using the dbms_space
package but it just seems to
complicated.
any hints ... ?
 

thank you
