If the cut is parallel to the long dimension, then each piece is 40 inches long, but its width is 1/2 of the original board's width. If the cut is parallel to the short dimension, then the width is preserved, and each piece is 20 inches long. If the cut is parallel to to the flat, then each piece is 40 inches long and has the original width, but is only 1/2 the thickness of the original board.

A concave long board isn't really any different from any other board except that it has a certain amount of pressure added to the center of the board so the edges are higher up. This adds a little more responsiveness to the turning and also helps you stay on the board better then if it was flat. Other variations of this would be like a "W" type concave.
