This is an irregular quadrilateral with given side lengths, not a three-dimensional shape, so it doesn’t have a "volume." However, we can calculate its area by dividing it into simpler shapes.

Steps to Find the Area:

1. Split into Two Triangles: The shape can be divided along the red-dashed lines, creating two right triangles.
2. Calculate Each Triangle's Area: We’ll use the area formula for each right triangle: $\text{Area of a triangle} = \frac{1}{2} \times \text{base} \times \text{height}$

Triangle 1:

• Base = $8$ cm
• Height = $6$ cm
• Area = $\frac{1}{2} \times 8 \times 6 = 24 \, \text{cm}^2$

Triangle 2:

• Base = $14$ cm (total bottom length) - $8$ cm (other triangle's base) = $6$ cm
• Height = $5$ cm
• Area = $\frac{1}{2} \times 6 \times 5 = 15 \, \text{cm}^2$

Total Area

By adding both triangle areas, we get: $\text{Total Area} = 24 + 15 = 39 \, \text{cm}^2$

Final Answer:

The area of this irregular quadrilateral is 39 cm².
