Which of the following finished patterns can be obtained from the piece of cardboard shown below?

The correct finished pattern that can be obtained from the given cardboard net is option (d).

Step 1: Understanding the question

The image shows a flat net of a cardboard box. Nets are 2D shapes that can be folded into 3D objects. In this reasoning problem, we are asked to visualize how the cardboard folds and which option matches the final figure. The options (a), (b), (c), and (d) represent different possible folded boxes, and we need to choose the one that fits perfectly.

Step 2: Features of the given net

• The net has four main rectangular faces arranged vertically like a long strip.
• Two extra flaps are attached on opposite sides of the strip. These act as closures when the cardboard is folded.
• On the top face, there is a circular design with diagonal lines that looks like a crossed envelope pattern.
• On one side, there is a small dark rectangular marking, which also must align correctly when the net folds.

Step 3: Visualizing the folding

When we fold the strip of rectangles, it forms a box with a front face, back face, and two side faces. The extra flaps close the top and bottom. The special marking (circle with cross) will appear on the main front panel. The small dark rectangle will align at the side edge. Thus, the front of the finished box must show both the crossed circle design and the side marking.

Step 4: Elimination of wrong options

• Option (a): Shows the circular cross design but the position of the side marking does not align correctly with the folding of the net.
• Option (b): Missing the circular cross pattern entirely, so it cannot match.
• Option (c): Again shows only a plain box with markings at the wrong place, no circle cross pattern.
• Option (d): Correctly shows the crossed circle design at the front and the side marking aligned at the edge, matching the given cardboard net.

Step 5: Final Answer

From the analysis, only option (d) can be obtained by folding the given cardboard net. This option respects both the design alignment and the placement of the side marking.
