Questions: How many significant figures are in the measurement 1.3000 meters? A. ? two B. ? four C. ? three D. ? five

Solution Steps

Significant figures in a measurement include all the digits that are known with certainty plus one final digit, which is somewhat uncertain or estimated.

The measurement given is 1.3000 meters. Here, all the digits (1, 3, 0, 0, 0) are significant because:

• The digit 1 is non-zero and significant.
• The digit 3 is non-zero and significant.
• The trailing zeros (0, 0, 0) after the decimal point are significant because they indicate the precision of the measurement.
