Find the cubes of :
`0.4`

Answer

To find the cube of \(0.4\), we will follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Cubing**:
The cube of a number \(x\) is calculated as \(x \times x \times x\). In this case, we need to find \(0.4 \times 0.4 \times 0.4\).

2. **Multiply the First Two Numbers**:
Start by multiplying the first two \(0.4\)s together:
\[ 0.4 \times 0.4 = 0.16 \]
(Here, \(4 \times 4 = 16\), and since we have two decimal places in \(0.4\), we place the decimal point after two digits in the result.)

3. **Multiply the Result by the Third \(0.4\)**:
Now, take the result \(0.16\) and multiply it by the third \(0.4\):
\[ 0.16 \times 0.4 \]
To perform this multiplication, we can break it down:
\[ 0.16 \times 0.4 = 0.16 \times \frac{4}{10} = \frac{0.16 \times 4}{10} = \frac{0.64}{10} = 0.064 \]

4. **Final Result**:
Therefore, the cube of \(0.4\) is:
\[ 0.4^3 = 0.064 \]

### Final Answer:
The cube of \(0.4\) is \(0.064\).
