The problem asks us to evaluate the expression $0.5^3$.

1. Problem Description

The problem asks us to evaluate the expression $0.5^3$.

2. Solution Steps

We need to calculate $0.5^3$. This means $0.5 \times 0.5 \times 0.5$.

First, calculate $0.5 \times 0.5 = 0.25$.

Then, calculate $0.25 \times 0.5 = 0.125$.

Alternatively, we can write $0.5$ as $\frac{1}{2}$.

Then, $0.5^3 = (\frac{1}{2})^3 = \frac{1^3}{2^3} = \frac{1}{8}$.

Converting $\frac{1}{8}$ to decimal form, we get $0.125$.

3. Final Answer

0. 125
