You can fold a net of a shape to
make that shape. This rectangular prism has four
pink faces that are rectangles and two green faces that are squares. This net has some faces that are
triangles and a face that is a square. What shape will it make? A, B, or C.

Let’s begin by looking at the
rectangular prism. We can call the two green faces
the base because these are the squares that make this a rectangular prism. So what makes it a prism are the
four pink faces that wrap around the bases. So notice that this base is a
square and the rest of the faces are triangles. So this is in a prism. These triangles fold up together to
create a pyramid. So we need to choose a shape that
has a square base and then made up of triangular faces around it.

Option A has a circular base. So it’s like a circular pyramid,
but it’s actually called a cone. Option B has a square base and is
made up of triangular faces. So that might be it. Option C has two circular
bases. And if we would unfold what wraps
around those circles, it would be a rectangle. So that’s actually a prism and we
call that a cylinder.

Therefore, option B is our square
pyramid. That is what our shape will
make.
