A tetrahedron (not rectangular) has vertices at $A, B, C,$ and $D .$ The length of the altitude from $A$ to the base $(\triangle B C D)$ measures 6 in. It is given that $\mathrm{m} \angle B C D=90^{\circ}$ $B C=4$ in., and $C D=8$ in. a) Find the volume of the pyramid. b) Find the length of the altitude from vertex $D$ to the base $(\triangle A B C)$; note that $A_{A B C}=12$ in $^{2}$ (FIGURE CAN'T COPY)
