Find the cube root of 216000.

• A. 10
• B. 90
• C. 60
• D. 216

Answer 1

The correct option is C 60

Given number is 216000.
$216000=216\times 1000\therefore \sqrt[3]{3216000}=\sqrt[3]{3216\times 1000}$
We know that, $216=6^3\text{and}1000={10}^3$

$\Rightarrow \sqrt[3]{3216000}=\sqrt[3]{36^3\times {10}^3}=6\times 10$
So, the value off $\sqrt[3]{3216000}\text{is}60$
