During an all-night cram session, a student heats up a 0.668 liter (0.668 x 10- 3 m3) glass (Pyrex) beaker of cold coffee. Initially, the temperature is 16.8 °C, and the beaker is filled to the brim. A short time later when the student returns, the temperature has risen to 93.8 °C. The coefficient of volume expansion of coffee is the same as that of water. How much coffee (in cubic meters) has spilled out of the beaker?
