To convert feet to inches for the distance, you would want to multiply the number of feet by the conversion factor of 12 inches per foot.
Thus, the correct response is:
Converting feet to inches by multiplying 10 feet by 12 inches/1 foot.
This can simply be expressed as \( 10 \text{ feet} \times 12 \text{ inches/foot} = 120 \text{ inches} \).
