Question

Find the cube root of 0.125

• A. 10
• B. 12
• C. 13
• D. 15

Answer 1

The correct option is B

12

0.125 can be written as $\frac{125}{1000}$

We need to find the cube root of it which is $\sqrt[3]{3\frac{125}{1000}}$

125 = $5^3$

1000 = ${10}^3$

So, $\sqrt[3]{3\frac{125}{1000}}$ = $\sqrt[3]{3\frac{5^3}{{10}^3}}$

= $\frac{5}{10}$ = 0.5
