The paper as shown in the figure is folded to make a cube where each square…

Answer: The cube that shows the hollow triangle on the front, the filled circle on the top, and the filled small triangle on the right matches the net.

Key steps to see why:

• Identify the centre square of the net as the front face; it contains the hollow triangle.

• The square directly above the centre becomes the top face when folded; that square contains the filled circle, so the top of the cube must show the filled circle.

• The square directly to the right of the centre becomes the right face; it contains the filled small triangle, so the right face must show that filled small triangle.

• The square below the centre becomes the bottom face and carries the hollow circle; this mark will not be visible from the front view but must be in that position.

Compare candidate cubes by checking these relative positions (front, top, right, bottom). The correct cube is the one that places the hollow triangle on the front, the filled circle on the top, and the filled small triangle on the right.
