Let's solve each question on the
"Solid Nets" worksheet by matching each 3D solid shape with its correct
net (a 2D pattern that can be folded to form the 3D shape).
---
1) Cone
- The cone has a
circular base and a
curved surface that tapers to a point.
- When unfolded, the curved surface becomes a
sector of a circle, and the base is a
circle.
✔ Correct net: a)
It shows a sector (part of a circle) with a small circle attached — this represents the lateral surface and base of the cone.
>
✔ Answer: a)
---
2) Triangular Prism
- A triangular prism has
two triangular bases and
three rectangular faces.
- The net must include
two triangles and
three rectangles connected properly.
✔ Correct net: b)
It shows two triangles at the ends and three rectangles in the middle — perfect for folding into a triangular prism.
>
✔ Answer: b)
---
3) Square Pyramid
- This has a
square base and
four triangular faces meeting at a point.
- The net should have
one square and
four triangles attached to each side.
✔ Correct net: c)
It shows a central square with four triangles around it — ideal for forming a square pyramid.
>
✔ Answer: c)
---
4) Cylinder
- A cylinder has
two circular bases and a
rectangular lateral surface.
- When unfolded, the side becomes a rectangle, and the top and bottom are circles.
✔ Correct net: b)
It shows a rectangle with a circle on each end — this folds into a cylinder.
>
✔ Answer: b)
---
5) Tetrahedron (Triangular Pyramid)
- A tetrahedron has
four triangular faces.
- The net must consist of
four triangles connected so they can fold into a pyramid.
✔ Correct net: a)
It shows four triangles arranged in a way that one triangle is central, and the other three are attached — this is a valid net for a tetrahedron.
>
✔ Answer: a)
---
6) Hexagonal Prism
- A hexagonal prism has
two hexagonal bases and
six rectangular sides.
- The net should show
two hexagons and
six rectangles connecting them.
✔ Correct net: b)
It shows a long strip of six rectangles with a hexagon on each end — this matches the structure of a hexagonal prism.
>
✔ Answer: b)
---
7) Cube
- A cube has
six square faces.
- The net must have six squares arranged so they fold into a cube.
✔ Correct net: a)
This is a classic "T" shaped net with six squares — it can fold into a cube.
>
✔ Answer: a)
---
✔ Final Answers:
1) a
2) b
3) c
4) b
5) a
6) b
7) a

🔍 Explanation Summary:
Each net must have the correct number and type of faces, and they must be arranged so that when folded, they form the 3D shape without overlaps or gaps. We matched each shape based on:
- Number of faces
- Shape of faces
- How they connect
