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 need to find the volume of a cubical body given the angle of shear and the change in length. Here’s a step-by-step solution:

### Step 1: Understand the relationship between shear angle and change in length
The angle of shear (φ) is related to the change in length (ΔL) and the original length (L) of the cube. The relationship can be expressed using the tangent function:
\[ \tan(\phi) = \frac{\Delta L}{L} \]
