Question

The cube of $0.4$ is $0.064$. State whether the statement is true (T) or false (F).

• A. True
• B. False

Answer 1

The correct option is A True

We will express $0.4$ in the form of a fraction.

$0.4$$=\frac{4}{10}$

Cube of $0.4$ can be written as

$$\begin{gathered} {\left(0.4\right)}^3={\left(\frac{4}{10}\right)}^3 \\ =\frac{4\times 4\times 4}{10\times 10\times 10} \\ =\frac{64}{100} \\ =0.064 \end{gathered}$$

Hence, the cube of $0.4$ is $0.064$.

Therefore, the given statement is true.
