There is the way involving the angle between the two vectors (which you have used in some other problems you posted here.)

Wikipedia says:
[tex]\mathbf{a}\times\mathbf{b}= \begin{vmatrix}
\mathbf{i} & \mathbf{j} & \mathbf{k} \\
a_1 & a_2 & a_3 \\
b_1 & b_2 & b_3 \\
\end{vmatrix}[/tex]
:smile: (but that's equivalent to what you already mentioned)
