If the angle of shear is `30^(@)` for a cubical body and the change in length is 250 cm, then what must be the volume of this cubical body.

Explanation

To solve the problem, we will follow these steps:

### Step 1: Understand the given information
We know that:
- The angle of shear (φ) = 30 degrees
- The change in length (ΔL) = 250 cm = 2.5 m (since we convert cm to m for consistency in units)

### Step 2: Calculate the shear strain
