Answer: 108 inches
Step-by-step explanation: To convert 9 feet into inches, we use the conversion factor for feet and inches which is 12 inches = 1 foot.
Next, notice that we're going from a
larger unit, feet, to a smaller unit, inches.
When we go from a larger unit to a smaller unit, we
multiply 9 by the conversion factor, 12 to get 108.
So 9 feet = 108 inches.
