The measurement 111.009 mm rounded to four significant digits is 111.0 mm. When rounding, the first four significant digits are 1, 1, 1, and 0, while the following digit (the next 0) does not affect the rounding. Therefore, the final result remains at one decimal place.

The measurement 1456 mm has four significant figures. All non-zero digits are considered significant, and since there are no leading zeros or decimal points that would affect the count, each digit (1, 4, 5, and 6) is significant.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
Only 1004.

7.2 mm because you round to the least specific decimal place, which is the tenths place on the first measurement.The product of of 2.2 mm and 5.00 mm is 11.00 to 4 significant figures.
18 mm = 0.71 inches. Since the first measure is to 2 significant digits it is not appropriate to give the answer to several sig figs. Direct Conversion Formula 18 mm* 1 in 25.4 mm = 0.7086614173 in
