You need to create a corridor datum surface and boundary, then create corridor sample lines and sections. Then you can use the quantity takeoff command in the sections menu.
I recommend that you do the tutorials for "Viewing and Rendering a Corridor", "Creating Cross Sections on an Alignment", and "Quantity Takeoff from Corridor Models".
The tutorials can be found in the 'Help > Civil 3D Tutorials' menu. They don't take very long and should help you more than I could by trying to explain it in this post.
To get what you want you can skip "Rendering Corridors" in the "Viewing and Rendering a Corridor" tutorial.
