Let's determine the number of significant figures in the number 18.03.
To count the number of significant figures, follow these rules:
1. All non-zero digits are considered significant.
2. Any zeros between significant digits are also considered significant.
3. Leading zeros (zeros before non-zero digits) are not significant.
4. Trailing zeros in a number containing a decimal point are significant.
Now, apply these rules to the number 18.03.
- The digits 1 and 8 are non-zero and therefore significant.
- The digit 0 is between two significant digits (1, 8, and 3) and hence is also significant.
- The digit 3 is non-zero and significant.
Therefore, the number 18.03 has a total of four significant figures.
Based on this detailed analysis:
The statement "The number 18.03 has three significant figures" is:
B. False
