Let \( \overrightarrow{P R}=3 \hat{i}+\hat{j}-2 \hat{k} \) and \( \overrightarrow{S Q}=\hat{i}-3 \hat{j}-4 \hat{k} \) determine diagonals of a parallelogram \( P Q R S \), and \( \overrightarrow{P T}=\hat{i}+2 \hat{j}+3 \hat{k} \) be another vector. Then the volume of the parallelepiped determined by the vectors \( \overrightarrow{P T}, \overrightarrow{P Q} \) and \( \overrightarrow{P S} \) is
