Physics help with heat and temperature?

During an all-night cram session, a student heats up a (0.5 10-3 m3) gl (Pyrex) beaker of cold coffee. Initially, the temperature is 18�C, and the beaker is filled to the brim. A short time later when the student returns, the temperature has risen to 92�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?
