The image you've uploaded is a
net (a 2D layout) for constructing a
square-based pyramid, which is a 3D geometric shape with a square base and four triangular faces that meet at a single point (the apex). This net includes instructions for assembling the pyramid. Let's break down the task and explain how to solve it.

🔷 Understanding the Task
You are given:
- A flat, printable template of a square-based pyramid.
- Instructions on how to cut, fold, and glue it to form a 3D pyramid.
Your goal:
Construct a square-based pyramid using this net.
---
✔ Step-by-Step Solution
####
1. Cut Along the Outside Edge
- Use scissors to carefully cut along the
outer solid lines of the net.
- This will separate the entire shape from the rest of the paper.
- The resulting shape should look like a central square with four triangles attached to each side — one on each edge.
> 📌 Tip: Be precise to ensure all edges match when folding.
---
####
2. Fold Inward Along the Inside Lines
- The
dashed or internal lines indicate where to fold.
- Fold each triangle
inward toward the center square along these lines.
- These folds will create the
triangular faces of the pyramid.
> 🔍 Each triangle will eventually meet at the top (apex) of the pyramid.

####
3. Glue the Flaps to Hold the Pyramid
- There are small extensions labeled "
Glue map" on each triangle.
- Apply glue to these flaps.
- Fold the triangles upward and
glue the flaps to adjacent triangles so they meet at the apex.
- Ensure the
edges align and the pyramid holds its shape.
> 💡 The glue maps help secure the structure without overlapping too much.

🔎 Geometry Insight
- A
square-based pyramid has:
-
1 square base
-
4 triangular faces
-
5 vertices (4 at the base + 1 apex)
-
8 edges (4 base edges + 4 slant edges)
This net represents the
surface area of the pyramid when unfolded.

✔ Final Result
After following the steps, you’ll have a
3D square-based pyramid, similar to the shaded illustration in the top-left corner of the image.

📝 Summary
To solve the problem:
1.
Cut the outer outline.
2.
Fold along the inner lines inward.
3.
Glue the "glue map" flaps to assemble the pyramid.
✔ You now have a completed
square-based pyramid model!
