Find the cube root of the following number by finding their units and ten digits:

$46656$

The correct option is B ($36$)

Given number $46656$
Here, the unit digit is $6$.
$\therefore$ The unit digit of the cube root is $6.$
$\because 6^3=216$, and also here unit digit $6$ is matching with unit digit of given number.
After striking out the last three digits from the right, the number left is $46.$
Now, $3^3=27<46$ and $4^3=64>46$
The ten-digit of the cube root is $3$ and $4$ can't be possible as $64>46$
$\therefore \sqrt[3]{346656}=36$
