A person's Body Mass Index is $I=\frac{W}{H^2}$, where $W$ is the body weight (in kilograms) and $H$ is the body height (in meters). Estimate the change in height that will decrease $I$ by 1 if $(W,H)=(27,1.3)$, assuming that $W$ remains constant. (Use decimal notation. Give your answer to three decimal places.)
