The measurement of the edge of a cube is measured to be 11 inches, with a possible error of 0.03 inch. Use differentials to approximate the possible error and the relative error in computing the following values. (Round your answers to three decimal places.) (a) the volume of the cube possible error: 1089 q in3 relative error i 8,181 x (b) the surface area of the cube possible errori 0/ in2 relative error 1 X
