88. The vector A is 3.50cm long and is directed into this page. Vector $\overrightarrow{\boldsymbol{B}}$ points from the lower right comer of this page to the upper left comer of this page. Define an appropriate right-handed coordinate system and find the three components of the vector product $\overrightarrow{\boldsymbol{A}} \times \overrightarrow{\boldsymbol{B}}$, measured in $\mathrm{cm}^{2} .$ In a diagram, show your coordinate system and the vectors $\vec{A}, \vec{B}$, and $\vec{A} \times \vec{B}$
