Answer
$\dfrac{6}{ 7}$
Work Step by Step
The formula to calculate the distance for two vectors is given by:
$d=\dfrac{|u \cdot v|}{|v|}$
Thus, we have $u \cdot v=0(3)+0(2)+1(6)=6$
and $|u \times v|=|6|=6$
Now, $d=\dfrac{|u \cdot v|}{|v|}=\dfrac{6}{ \sqrt {(3)^2+(2)^2+(6)^2}}=\dfrac{6}{ \sqrt {49}}=\dfrac{6}{ 7}$
