Given information:
The given information states that there is a closed surface defined by the following parameters:
- Surface = 2
- Surface = 4
- Surface = 450
- Surface = 1350
- z = 3
- z = 4

To find:
We need to find the total area of the enclosing surface.

Explanation:
To find the total area of the enclosing surface, we need to calculate the area of each surface and then add them up.

Calculating the area of the surfaces:
1. Surface = 2:
This surface does not provide any information about its dimensions, so we cannot calculate its area. Therefore, we cannot consider it in the total area calculation.

2. Surface = 4:
Similarly, this surface does not provide any information about its dimensions, so we cannot calculate its area. Therefore, we cannot consider it in the total area calculation.

3. Surface = 450:
Since the surface is not defined by any specific shape or dimensions, we cannot calculate its area. Therefore, we cannot consider it in the total area calculation.

4. Surface = 1350:
Again, since the surface is not defined by any specific shape or dimensions, we cannot calculate its area. Therefore, we cannot consider it in the total area calculation.

5. z = 3:
This surface is defined by a plane perpendicular to the z-axis at z = 3. Since we do not have any information about the dimensions or shape of this plane, we cannot calculate its area. Therefore, we cannot consider it in the total area calculation.

6. z = 4:
This surface is defined by a plane perpendicular to the z-axis at z = 4. Similarly, we do not have any information about the dimensions or shape of this plane, so we cannot calculate its area. Therefore, we cannot consider it in the total area calculation.

Conclusion:
Based on the given information, we cannot calculate the total area of the enclosing surface because we do not have enough information about the dimensions or shapes of the surfaces involved. Therefore, none of the provided options (A, B, C, or D) is correct.
