Scalar Triple Product of Vectors

Let $\vec a{\text { }} = 2\hat i - 3\hat j + \hat k$ , $\vec b{\text { }} = 3\hat i + 2\hat j + 5\hat k$ and a vector $\overrightarrow c$ be such that $\left( {\vec a - \vec c} \right) \times \vec b{\text { }} = - 18\hat i - 3\hat j + 12\hat k$ and $\overrightarrow a .\overrightarrow c = 3$ . If $\overrightarrow b \times \overrightarrow c = \overrightarrow d$ , then $\left| {\overrightarrow a .\overrightarrow d } \right|$ is equal to :
