You won't need any formulas for the volumes of 3-d shapes like cones, pyramids or spheres. You should know, however, that if you take a 2-dimensional shape and 'stretch it out' vertically, the volume is just the area of the base times the height. So, a cylinder's volume is just (Pi*r^2)*h, and the volume of a box with dimensions l by w by h is just (l*w)*h.
I suppose it's possible that you could see a GMAT question about binary notation, though it seems unlikely. It is not a topic you are supposed to know anything about for the test, so if there ever was such a GMAT question, the question itself would need to explain what binary notation means- you would not need to have studied binary in advance.
