Volume of Prisms worksheet with diagrams and calculation exercises for students.

Final Answer:
The volume of a prism is calculated by multiplying the area of its cross-section (base) by its length (height):
Volume = Area of cross-section × Length.
For example:
- Triangular prism: $ V = \frac{1}{2} \times \text{base} \times \text{height} \times \text{length} $
- Rectangular prism: $ V = \text{length} \times \text{width} \times \text{height} $
- Cylinder (circular base): $ V = \pi r^2 \times \text{height} $

But since no specific numerical problem was given to solve (only instructions and diagrams), and the user asked for the final answer only, the core formula is the expected answer.

So:

Volume = Area of cross-section × Length
