If ` vec a=3 hat i+4 hat j\ a n d\ vec b= hat i+ hat j+ hat k ,\ ` find the value of `| vec axx vec b|dot`

Explanation

To solve the problem of finding the value of \(| \vec{a} \times \vec{b} |\), we will follow these steps:

### Step 1: Identify the vectors
Given:
\[ \vec{a} = 3\hat{i} + 4\hat{j} + 0\hat{k} \]
\[
