The 12 ft squared is the area of the base. The area of a recktangle is length x width. So the base's area would be 6x2 = 12 ft squared.
Length x width x height would equal volume, the space/mass inside the hutch.
6 x 2 x 2 = 24 ft cubed.
The area is the space inside the shape, the size it's taking up. So the hutch would be taking up 12ft of your room, 6 ft in length and 2 ft in width.
The volume is the mass inside the shape, so your hutch will be taking up 24 ft cubed of your room's mass.
Your dresser's area is 35 x 20 = 700 inches squared. That's how much space it'll take up on the floor.
If you remove the dresser from the room, you'll have 700 inches squared more space.
Your dresser's size could be
1 inch x 700 inches
2 inches x 350 inches
50 inches x 14 inches
The area that any of the dressers would be taking would always be 700 inches squared
:wave: hope that makes sense, I think most of what I said hasn't answered your questions
