Help - Can a 3 dimensional part be expressed in Linear Feet?

I am trying to find 3 ways to determine or equalize surface area. I have a 1ft wide x 12ft long x 1inch deep piece of metal rail. I have determined the area to be 3768 Sq Inch. correct? if so it is equivalent to 26.16 Sq Ft. correct? I cannot figure out the corresponding measurement in linear Ft. I came up with 12.56 Lin Ft, but not sure how or if it is correct.

In considering linear feet - I would expect the piece to simply be 12 lin Ft, however I have to take into consideration the depth of the piece. ie - the surface area has to go up as the depth of the part goes up - correct?

Thanks -
