A solid steel cube is stored in a freezer, where the temperature is -20.0 °C. While the cube is in the freezer, you measure its side length (L) to be 1.75050 meters. The cube is then placed outside for a long time, so that the temperature of the cube reaches the temperature of the air outside. As a result, the side length increases to 1.75170 meters due to thermal expansion. The coefficient of linear expansion for steel is 12.0×10-6 °C-1. (a) What is the temperature of the air outside? Give your answer in degrees Celsius (°C). (b) What is the volume of the cube when its temperature is 20.0 °C? Give your answer in cubic meters (m³).
