M: The standard unit is 3.2 meters wide, 1.8 meters tall and 30 centimeters deep. W: Thanks. That's the dimension I need. How about the colors? M: We have four choices, white, black, brown and gray. W: I think brown is okay. Now what about the charge of the delivery? M: Well, it depends on how far you are from our factory. W: We're about five miles from your factory. M: I see. That's in our free delivery area. (8)
