From the kinetic theory of gases, predict the effect on the pressure of a gas inside a cubic box of side l by reducing the size so that each side measures l/2.

Explanation

To solve the problem of predicting the effect on the pressure of a gas inside a cubic box when the size is reduced from side length \( l \) to \( \frac{l}{2} \), we can use the ideal gas law and the relationship between pressure and volume.

### Step-by-Step Solution:

1. **Understand the Initial Conditions**:
- The initial side length of the cube is \( l \).
- The initial volume \( V_1 \) of the cube can be calculated as:
\[
