Please type your subject in the School Subject box. Any other words are likely to delay responses from a teacher who knows that subject well.
I would agree that this is not first grade math at all. The only thing that I could come up with is a cube. I didn't learn anything like this when I was in first grade.
Remember that a vertex can be the point opposite the base.
So what is a triangular pyramid (4 sides) which is sitting on its point? 4 sides, 3 vertexes
This is 4th grade math.
