The distance between telephone poles is 30.5 m in a neighborhood where the temperature ranges from -35 °C to 40 °C. If you hang a copper cable between two adjacent poles on a day when the temperature is 22.3 °C, what is the minimum length of the copper cable you must use for the cable to remain connected to the poles all year? Assume the cable is straight, and ignore the effect of gravity on the cable.
