5832 ended with 2 , so it's cube root should end with 8

Let's check it out,

Cube root of 5832

$\sqrt[3]{5832}$


$= \sqrt[3]{18\times 18 \times 18 } \\ \\ = \sqrt[3]{ {18}^{3} } \\ \\ = 18$

Therefore, Cube root of 5832 ends with 8 or

you can say that, Digit in the units place of cube root of 5832 is 8
