I guess you do not have 'Select any table' privilege,
Be granted 'Select any table' by SYS or any DBA user. then try.
SELECT Total.name "Tablespace Name",
        nvl(Free_space, 0) Free_space,
        nvl(total_space-Free_space, 0) Used_space,
        total_space
FROM
   (select tablespace_name, sum(bytes/1024/1024) Free_Space
      from sys.dba_free_space
     group by tablespace_name
   ) Free,
   (select b.name,  sum(bytes/1024/1024) TOTAL_SPACE
      from sys.v_$datafile a, sys.v_$tablespace B
     where a.ts# = b.ts#
     group by b.name
   ) Total
WHERE Free.Tablespace_name(+) = Total.name
and Free.Tablespace_name='USERS'
ORDER BY Total.name
Tablespace Name                FREE_SPACE USED_SPACE TOTAL_SPACE
USERS                             38.1875    11.8125          50
