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]

(but that's equivalent to what you already mentioned)
