forgive me mathteacher, but im gonna correct you here, board volume is not the dimensions. knowing your volume is a good thing. if you look at a board, itll typically give you the length, width at midpoint, and thickness at midpoint. Two different boards could have those dimensions, but have different volume, because every measurement in between could be different. a lot of boards will hide volume throughout the board. the foil might stay thicker throughout the length of a board, or may get thin at the nose and tail.
it isnt something that you will likely pay attention to as a beginner, because youll probably be riding a bigger board. however, as you advance, and possibly want to go shorter (as you go shorter, if thats your choice, volume is much more of a factor than on a longboard), youll eventually dial in a board that is the right float/volume for your weight. so you ask, whats the volume of my board then? short of somehow measuring the amount of water it displaces, it is a figure you would have to get from the board manufacturer. many shapers are now including the volume in cubic liters, along with the dimensions of the board.
take a look at this pagehttp://www.lostsurfboards.net/surfboards/monkfish/
notice the list of stock dimensions
5’6 19.50 2.25(27.0cl)
5’8 20.00 2.38 (29.9cl)
5’10 20.25 2.44 (31.8cl)
the figure in parentheses is the volume in cubic liters. so lets say you know you love the 5'8. Its the perfect float/paddle for you. You take note of the volume, 29.9cl. Now, if youre looking at another board to buy, how it floats you is no longer a guesstimate. You could mess around with the dimensions, making it wider and shorter, longer and narrower, etc., knowing that as long as your board is around 29.9, itll float you the same.
