Welcome net detective, we’ve got a puzzle just for you!
Look at the following 3D shape:
It is a triangular-based pyramid.
If we unfold it, it could look like this:
We call this a net.
A net is made of 2D shapes which fold together to make a 3D shape.
These nets could also fold together to make a triangular-based pyramid:
Let's try another now.
Imagine that the following net is folded together:
What would it look like?
a) b) c) d)
Did you choose option d?
This is the only net from these options that can be folded together to make a square-based pyramid.
Here are some common 3D shapes and their nets:

It’s now your turn to visualise folding nets together to see what shape they will make.
Pssstt!! Here’s a handy hint to help you reach superstar status:
If it helps, you can draw the net on a piece of paper and fold it together.
Good luck, 3D shape superstar!
