Let’s go row by row and match each 3D shape to its correct net (the flat pattern that folds into it).
---
Row 1: Dodecahedron (12 pentagon faces)
→ Look for a net made of 12 pentagons connected in a way that can fold into a ball-like shape.
✔ The
fourth option (rightmost) is the correct net — it has pentagons arranged like a flower, which matches how a dodecahedron unfolds.
---
Row 2: Icosahedron (20 triangle faces)
→ Needs a net with 20 triangles.
✔ The
third option (star-shaped with many small triangles) is the right one — it’s the classic star-net for an icosahedron.
---
Row 3: Octahedron (8 triangle faces)
→ Should have 8 equilateral triangles.
✔ The
first option (diamond shape with 4 triangles on top and 4 on bottom) is correct — it folds into two pyramids stuck together at the base.
---
Row 4: Square Pyramid (1 square base + 4 triangle sides)
→ Net should have 1 square and 4 triangles attached to its sides.
✔ The
second option (square in middle, triangles on all four sides) is perfect.
---
Row 5: Cube (6 square faces)
→ Classic cube net: 6 squares arranged so they can fold into a box.
✔ The
fourth option (cross shape: 4 squares in a line, one above and one below the center) is the standard cube net.

Now let’s shade the correct ones:
- Row 1 → Shade column 4
- Row 2 → Shade column 3
- Row 3 → Shade column 1
- Row 4 → Shade column 2
- Row 5 → Shade column 4
---
Final Answer:
Shade these positions:
Row 1, Column 4
Row 2, Column 3
Row 3, Column 1
Row 4, Column 2
Row 5, Column 4
