Sure, here's a problem for the student to solve:

Astronomers have detected possible signals of WIMPs in a particular region of the sky. The signals are found to have energy of 40 GeV and to be produced by interactions between WIMPs and atomic nuclei. The total number of WIMPS produced is estimated to be 1,000 per year in a volume of 1 cubic meter. Suppose the mass density of dark matter in this region is 0.2 GeV/cm^3. 

What is the total mass of dark matter in this region? Compare this to the mass of visible matter (stars, gas, etc.) in the same region, which is estimated to be 10^12 solar masses. Can WIMPs account for the missing mass in this region?
