Question

Making use of the cube root table, find the cube root
0.27

Answer 1

The number 0.27 can be written as $\frac{27}{100}$.

Now

$\sqrt[3]{0.27}=\sqrt[3]{\frac{27}{100}}=\frac{\sqrt[3]{27}}{\sqrt[3]{100}}=\frac{3}{\sqrt[3]{100}}$

By cube root table, we have:

$\sqrt[3]{100}=4.642$

$\therefore$ $\sqrt[3]{0.27}=\frac{3}{\sqrt[3]{100}}=\frac{3}{4.642}=0.646$

Thus, the required cube root is 0.646.
