Try
        select volume_name,cast((pct_utilized * est_capacity_mb / 100) as
decimal ) as "MB on Tape" from adsm.volumes where devclass_name='3590DEVC'
or
        select cast(sum(pct_utilized * est_capacity_mb / 100) as decimal )
as "MB on Tape" from adsm.volumes  where devclass_name='3590DEVC'

ie.
select cast(sum(pct_utilized * est_capacity_mb / 100) as decimal )
 as "MB on Tape" from adsm.volumes where devclass_name='3590DEVC'

         MB on Tape
