Answer :
To solve this problem, we need to convert the length of a standard 12-inch ruler into centimeters. Given that one inch is equivalent to 2.54 centimeters, we can determine the length in centimeters by multiplying the number of inches by the conversion factor (2.54 cm per inch).
Here are the steps to follow:
1. Determine the conversion factor: We know that 1 inch = 2.54 centimeters.
2. Identify the number of inches in the ruler: A standard ruler has 12 inches.
3. Calculate the length in centimeters: To find how many centimeters the ruler measures, multiply the number of inches by the conversion factor.
[tex]\[
\text{Length in centimeters} = \text{Length in inches} \times \text{Conversion factor}
\][/tex]
Substituting the values, we get:
[tex]\[
\text{Length in centimeters} = 12 \, \text{inches} \times 2.54 \, \text{cm/inch}
\][/tex]
4. Perform the multiplication:
[tex]\[
12 \times 2.54 = 30.48
\][/tex]
Thus, a 12-inch ruler is equivalent to 30.48 centimeters.
With this calculation, the correct answer is:
d) 30.48
