A rectаngulаr bоx hаs side lengths (x(t),, y(t),, z(t)) that change with time. At the instant when (x=2), (y=3), and (z=4), suppоse (dfrac{dx}{dt}=3), (dfrac{dy}{dt}=-2), and (dfrac{dz}{dt}=-1).Hоw fast is the volume (V) of the box changing at that instant? Enter your answer in the answer box below. (dfrac{dV}{dt}=)
