The correct answer is: $164.592\text{ cm}$
Explanation
You convert feet to centimeters using the exact conversion $1\text{ ft}=30.48\text{ cm}$. Multiply the number of feet by that conversion factor to get centimeters.
Steps:
- Formula: $1\text{ ft}=30.48\text{ cm}$
- Multiply: $$5.4\times30.48=164.592\text{ cm}$$
- Final answer: $164.592\text{ cm}$ (you can round to $164.59\text{ cm}$ or $165\text{ cm}$ depending on required precision)
Therefore, $5.4\text{ ft}=164.592\text{ cm}$.
