Given: 

250

To find: 

We have to find the cube root of the given number correct to three decimal places using cube root table.

Solution:

$\sqrt[3]{250}=\sqrt[3]{125 \times 2}$

$=\sqrt[3]{5 \times 5 \times 5 \times 2}$

$=\sqrt[3]{5^{3} \times 2}$

$=5 \sqrt[3]{2}$

$=5 \times 1.260$    (From the cube root table)

$=6.300$
