The height is the most uncertain thing we measured because we mostly had to rely on estimation and obscure math. The height of the library could not simply be measure like that width or length due to it’s vertical nature. The height could also be an issue as we measure the height of a single stair, counted the amount of stairs per floor, and then multiplied those number be the number of floors in the library. However with so many different factors the room for error increases exponentially. Additionally we might have been unable to take into account differences related to step height. Also, our lack of access to the upper levels of the library prevented us from being able to take into account the different dimensions of these floors that could have affected their height. The length and width were also uncertain in terms of the variations in brick length, but the height was the most difficult attribute to access. Based on the several issues noted above we estimated that we would arrive at a standard deviation of 1200m^3.
