There is a rod that is 55 cm long and 1 cm in radius that carries a 8 uC charge that is ditributed uniformly over its entire length. What would be the magnitude of the electric filed 4.0 mm from the ord surface, not near either?

So far I have 2(8*10^-6)(9*10^9)/.55=261818

then I divide that by 1.4 and get 1.9 *10^6 as my final answer, what did i do wrong

ARe you telling me that the spot you wanted was 1.4meters away from the center of the rod? hardly. You have to work these in meters.
