Answer
$18 \text{ ft}\approx 5.486\text{ m}$
Work Step by Step
If we want to convert from feet to meters, we have to consider the following conversion rate:
$ 1\text{ ft}=0.3048\text{ m}$
We multiply both sides by 18 in order to get the answer to the question:
$18 \text{ ft} =18\times 0.3048\text{ m}=5.4864\text{ m}$
After rounding to two decimal places:
$18 \text{ ft}\approx 5.486\text{ m}$
