Solution

Step 1: Identify the Significant Figures in Each Measurement

To determine the number of significant figures in each measurement, we need to analyze each option:

12.80 m: The number has four significant figures. The digits 1, 2, 8, and 0 are all significant.
0.1280 m: The number has four significant figures. The leading zeros are not significant, but the digits 1, 2, 8, and 0 are.
0.001280 m: The number has four significant figures. The leading zeros are not significant, but the digits 1, 2, 8, and 0 are.
1280 m: The number has three significant figures if the trailing zero is not considered significant (assuming no decimal point is present).

Step 2: Determine the Measurement with the Fewest Significant Figures

From the analysis above, the measurement with the fewest significant figures is 1280 m, which has three significant figures.
