Capitolo 1, Problema 94b
Perform each unit conversion. b. 116 ft to cm
Guida verificata passo dopo passo1
Identify the conversion factors needed: 1 foot (ft) is equal to 30.48 centimeters (cm).
Set up the conversion equation using the conversion factor: \( 116 \text{ ft} \times \frac{30.48 \text{ cm}}{1 \text{ ft}} \).
Cancel out the units of feet (ft) to leave the desired unit of centimeters (cm).
Multiply the numerical values: 116 by 30.48.
The result will give you the length in centimeters.
