Problem:

A long thin rod lies along the x-axis. One end is at x=1.00 m and the other at x=3.00 m. Its linear mass density lambda= 0.300 x20.600, in kg/m. Calculate mass of the rod.

The real problem is that apparently the professor explained this on monday and I didn't make it to the class. So really, any nudges in the right direction will be greatly appreciated.

Length * Linear Density = mass

You could also try some dimensional analysis.
