Consider the points \( A(2,-3,3), B(3,-5,0), C(-3,-4,0) \), and \( D(3,3,-6) \).
(a) Find the volume of the parallelepiped that has the vectors \( \overrightarrow{A B}, \overrightarrow{A C} \), and \( \overrightarrow{A D} \) as adjacent edges.
NOTE: Enter the exact answer.
Volume \( = \)
(b) Find the distance from \( D \) to the plane containing \( A, B \), and \( C \). NOTE: Enter the exact answer.
Distance \( = \)
