You can set up a ratio as follows:
Solve for x by cross-multiplying:
Since we need the answer in mm and right now we have it in feet, we need a conversion ratio. After googling it, the conversion ratio is: 1ft = 304.8mm
So, the answer is 14326.64 mm.

<h2>Answer:126 ways</h2>
Step-by-step explanation:
Given that the first digit could be any number from though
.
So,there are ways to choose the first digit.
Given that the second digit was either or
.
So,there are ways to choose the second digit.
Given that the third digit could be any number except .
So,there are ways to choose the third digit.
The number of different codes possible is the product of number of ways of choosing first digit,number of ways of choosing second digit and number of ways of choosing third digit.
Total ways are ways
