Let's review features of 3D objects to help us in this lesson.
Here is a rectangular prism.
How many faces does it have?
How many vertices does it have?
How many edges does it have?
A prism can be made with any polygon at its base.
Let's look at how to make 2D representations of 3D solid objects.
Choose the net that folds to give the shape below:
When we make a net of a solid, there may be more than one possibility. We can use the edges and vertices to help us, as well as the two dimensional (2D) shapes.
Connect three-dimensional objects with their nets and other two-dimensional representations
