For some context, I am learning about the cross product, and the matrix we used as an example was: $\mathbf{\text{V}}=\left[\begin{array}{c}\overrightarrow{{v}_{1}}\\ \overrightarrow{{v}_{2}}\\ \overrightarrow{{v}_{3}}\end{array}\right]$ which I am told is a $3\times 3$ matrix. But since these vectors are in 3 dimensions, wouldn't they also be column vectors? How do we get to a $3\times 3$ square from that?
