345.1

Explanation:

The significant digits are the digits that have measured not those that are the results of calculations. In the example above there are six digits. If only four of them are significant the problem must be rounded off to the nearest tenth, leaving only four digits.

345.06 is closer to 345.1 than to 345.0 so rounding to the nearest tenth gives

345.1
