Question

Use three unit multipliers to convert 45 feet to meters

Answer 1

1 inch = exactly 2.54 cm, by definition

1 foot = 12(2.54 cm) = 30.48 cm

1 meter = 100 cm

1 cm = 0.01 meters

1 foot = 30.48(.01)m = 0.3048 m

45 feet = 45(0.3048) = 13.716 meters

45 ft = exactly 13.716 m

Answer 2

1 inch = 2.54 cm

12 inches = 1 foot

1 meter = 100 cm

((45 feet)(12 inches/foot))(2.54 cm/inch)/(100 cm/meter) = 13.716 meters
