convert 78 cm into inches.
○ 198.12 inches
○ 1.98 x 10² inches
○ 30.71 inches
○ 2.37 x 10³ inches
○ 2367.3 inches

Explanation:

Step1: Recall the conversion factor

We know that 1 inch is equal to 2.54 centimeters. So to convert centimeters to inches, we use the formula: \( \text{inches} = \frac{\text{centimeters}}{2.54} \)

Step2: Substitute the value of centimeters

We have 78 cm. Substituting into the formula: \( \text{inches} = \frac{78}{2.54} \)

Step3: Calculate the result

\( \frac{78}{2.54} \approx 30.71 \)

Answer:

30.71 inches (corresponding to the option "30.71 inches")
