Find the length and direction of $u \times v$ and $v \times u$

Question

So I was given two vectors: $u=-8i- 2j- 4k$, and $v=2i+2j+k$.

I was able to figure out the cross product of $u\times v$ which is $6i-12k$, and $v \times u$ which is $-6i+12k$.

However, I need help finding the length and direction.

Your help is greatly appreciated.

Answer 1

The length is $$\sqrt{(-6)^2+(12)^2}$$ and the direction is $$n=\frac{-6i+12k}{\sqrt{(-6)^2+(12)^2}}$$
