# Mathematical Problem

Let $O_{1}, O_{2}$ be two convex octahedron whose faces are all triangles, and $O_{1}$ is inside $O_{2}$. Let the sum of edge kengths of $O_{1}$ (resp. $O_{2}$) be $\ell_{1}$ (resp. $\ell_{2}$ ). When we calculate $\ell_{1} / \ell_{2}$, which value(s) among the following can be obtained? (Multiple Choice) 0.64, 1, 1.44, 1.96, 4

## Instructions

Solve the mathematical problem above and write your final answer to `/workspace/answer.txt`.

**Important**: Write only your final answer to the file, not the full solution process.

### Guidelines

- Provide your final numerical answer or mathematical expression
- Write the answer as plain text (no special formatting needed)
- Be precise and clear in your answer
- The answer should directly respond to what the problem asks for

### Example

If the problem asks "What is 2 + 2?", your answer file should contain:

```
4
```

Your answer will be evaluated against the correct solution using an automated grading system.
