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 circle attached — this matches the cone.
>
✔ Answer:
a
---
2) Square Pyramid
- This shape has a
square base and
4 triangular faces meeting at a point (apex).
- The net should have a
square in the center with
4 triangles attached to each side.
✔ Correct net: b)
It shows a central square with 4 triangles extending from each side — perfect for a square pyramid.
>
✔ Answer:
b
---
3) Pentagonal Pyramid
- A pentagonal base with
5 triangular faces.
- The net should have a
pentagon with
5 triangles attached to each side.
✔ Correct net: c)
It shows a pentagon with 5 triangles around it — matches perfectly.
>
✔ Answer:
c
---
4) Cylinder
- A cylinder has
two circular bases and a
rectangular lateral surface.
- The net should show
two circles and a
rectangle (the side when unrolled).
✔ Correct net: b)
It shows a rectangle with a circle on each end — this forms a cylinder when rolled.
>
✔ Answer:
b
---
5) Tetrahedron (Triangular Pyramid)
- All faces are
triangles. It has
4 triangular faces.
- The net should consist of
4 connected triangles forming a star-like or zigzag pattern.
✔ Correct net: a)
It shows a central triangle with three other triangles attached — this can fold into a tetrahedron.
>
✔ Answer:
a
---
6) Hexagonal Prism
- A prism with
hexagonal bases and
6 rectangular sides.
- The net should have
two hexagons and
6 rectangles connecting them.
✔ Correct net: a)
It shows two hexagons with 6 rectangles between them — matches a hexagonal prism.
>
✔ Answer:
a
---
7) Rectangular Prism (Cuboid)
- Has
6 rectangular faces.
- The net must have
6 rectangles arranged so they fold into a box.
✔ Correct net: a)
It shows a cross-shaped arrangement of rectangles — common net for a rectangular prism.
>
✔ Answer:
a

🔍 Explanation Summary:
-
Nets are flat patterns that fold into 3D shapes.
- Each shape has specific features:
-
Cone: Sector + circle
-
Pyramids: Base + triangular faces
-
Prisms: Two bases + rectangular sides
-
Cylinder: Rectangle + two circles
By identifying the number and type of faces, you can match the correct net.
