Answer 1

To convert 3 feet to millimeters, multiply by 12 inches per foot and 25.4 millimeters per inch.

Step-by-step explanation:

To convert from feet to millimeters using conversion factors, we start with the given quantity of 3 feet. We know that there are 12 inches in 1 foot, and 25.4 millimeters in 1 inch. We can set up conversion factors to cancel out the units and calculate the answer:

Therefore, the answer is 914.4 mm (option a).
