The answer to the question is:
C. 2
To determine the number of significant figures in each value provided in the problem, we can follow these steps:
1. Understanding Significant Figures: Significant figures are the digits in a number that are known with a certain degree of reliability. The rules for determining significant figures are as follows:
- All non-zero digits are considered significant.
- Any zeros between non-zero digits are significant.
- Leading zeros are not significant.
- Trailing zeros to the right of the decimal point are significant.
- Trailing zeros in a whole number with the decimal shown are significant (e.g., 100. has 3 significant figures).
2. Evaluating the First Value (350 cubic inches):
- The number 350 has three digits: 3, 5, and 0.
- The zero is trailing, but since there is no decimal point shown, it is not considered significant.
- Therefore, the number 350 has two significant figures.
3. Evaluating the Second Value (5,500 cubic centimeters):
- The number 5,500 has four digits: 5, 5, and two zeros.
- The zeros are trailing, and without a decimal point, they are not considered significant.
- Therefore, the number 5,500 also has two significant figures.
Both 350 cubic inches and 5,500 cubic centimeters involve two significant figures based on the rules for significant figures.
