-Oh, dear, come on, solids! You need to get sorted.
Right. Small solids come to the front, and big solids go to the back.
Hey, watch out!
Not all solids are as solid as you.
There we go. That is better.
Wait a minute, you are still all mixed up.
No, no, that will not do. I have got an idea.
Prisms on one side and pyramids on the other.
I see, you are not sure, are you? Which ones of you are pyramids?
No, you are not.
But you are a very pretty little prism.
Look, you have got edges, rectangular sides,
and two identical faces.
Well done, you are fantastic.
There can be all sorts of different prisms,
whereas a pyramid is something else.
Let us see, you there, for example. Yes, you!
The one that looks like an Egyptian pyramid.
You, too, have got edges, vertices.
The base can have the shape of any type of polygon
and all the other faces
are triangles. It is easy, you see.
Prisms and pyramids can be drawn or unfolded.
To sum up, a prism has two identical ends
that are identical polygons.
All the other sides are parallelograms.
As for a pyramid, the base is a polygon,
all the other faces are triangles.
So, now, do you get it?
Pyramids on one side and prisms on the other.
That is it! Well done.
You are fantastic!
What about you? Do you not know where to go?
Look, you have two identical faces,
and all your other sides are rectangles.
So, you are a prism.
Oh, my! Solids! You are a tough lot to handle.
