===========================================================

Understanding the Problem

The given expression is a simple arithmetic operation involving fractions. The task is to evaluate the expression and determine the volume of a shape, which is not directly related to the expression. However, we will first focus on evaluating the expression and then discuss the volume.

Evaluating the Expression

The given expression is:

{ \frac{6}{12} + \frac{3}{12} + \frac{4}{12} = \frac{13}{12} \}

To evaluate this expression, we need to add the three fractions together. Since they have the same denominator (12), we can simply add the numerators (6, 3, and 4) and keep the denominator the same.

{ \frac{6}{12} + \frac{3}{12} + \frac{4}{12} = \frac{6+3+4}{12} = \frac{13}{12} \}

Therefore, the expression evaluates to $\frac{13}{12}$ .

Understanding the Volume Question

The question asks for the volume of a shape, but it does not provide any information about the shape or its dimensions. This seems to be a separate question from the expression evaluation. However, we can try to relate the expression to the volume question.

Relating the Expression to the Volume Question

Since the expression evaluates to $\frac{13}{12}$ , we can try to relate this to the volume question. However, without more information about the shape or its dimensions, it is difficult to determine the volume.

Possible Shapes and Volumes

Let's consider some possible shapes and their volumes:

Cube: The volume of a cube is given by $V = s^3$ , where $s$ is the side length.
Rectangular Prism: The volume of a rectangular prism is given by $V = lwh$ , where $l$ , $w$ , and $h$ are the length, width, and height, respectively.
Sphere: The volume of a sphere is given by $V = \frac{4}{3}\pi r^3$ , where $r$ is the radius.

Without more information about the shape or its dimensions, it is difficult to determine the volume.

Conclusion

The given expression evaluates to $\frac{13}{12}$ . However, the question about the volume of a shape is not directly related to the expression. Without more information about the shape or its dimensions, it is difficult to determine the volume.
