Hi - Do you know the coefficient of thermal expansion of the steel ruler?

If so, you can determine how much the the ruler expanded (from point 0 to point 21.93) at 345.0^{o}C.

Given that, you know the new length of the rod.

Try it, see if it works.

The coefficient of thermal expansion for steel is (10.5e-6), according to my book.
