Narrative:

I was pilot monitoring giving 3rd leg of IOE to first officer PF. At approximately 19NM from runway 06L direct dupay at 6000' we were cleared; 'cross dupay at or above 3000' cleared for ILS 6L.' PF selected lvl ch and speedbrakes; and began descent to 3000'. As we leveled off at 3000' just outside of dupay; ATC notified us 'you have departed class B airspace and are reentering; now.' our speed was approximately 230kts.we were unaware that we would be below the class B 15 miles from the runway at 3000'.closer study of the class B chart would require 200kts below 4000' outside of dupay. Or ride the GS down to dupay.
