If the six-digit number 214x35 is completely divisible by 9, find the value of "x". Also check whether the new num formed using this value of x is divisible by 3.

The notation "$3/216$" and "$3/125$" in the context of finding values, especially with other root questions on the paper, most likely refers to the cube root. So, the question is to find the value of $\sqrt[3]{216} \times \sqrt[3]{125}$.

This is because $6 \times 6 \times 6 = 216$.

This is because $5 \times 5 \times 5 = 125$.

The value of $\sqrt[3]{216} \times \sqrt[3]{125}$ is 30.

The final answer is $\text{30}$.
