Learn about 3 Dimensional Nets Three dimensional nets: So in this problem, it asks what three dimensional figure does each net make when folded? So, here we have four different figures and we need to figure out which three dimensional figure these form. Okay, before we move on let’s talk about nets and shapes for a minute. So, a polyhedron is a solid figure with faces that are polygons. Pyramids and prisms are types of polyhedrons. They’re known as three-dimensional figures of 3D figures. Now a net is a pattern made when the surface of three-dimensional figures is laid out flat showing each face of the figure. Now, a three-dimensional figure can be made from two-dimensional nets which when folded along the edges forms a respective 3D model. So, let’s take a look at our first shape. So, here we have this net. The net has two bases and four faces. Here is a base and here is a base and then these are the faces. When the net is folded along the edges, it forms a 3D figure as shown. This 3D figure is called a cube. Let’s move on to our second figure. So, in this figure, this net has two circular bases. So, we have a base here and a base here. Now, when this net is folded along the edges, it forms a 3S figure and this 3D figure is called a cylinder. Let’s move on to our next figure. So here, in this figure, this net has one square base and four triangular faces as shown here. Now, when this net is folded along the edges, it forms this 3D figure. This figure is called a square pyramid. Let’s move on to our last figure. So in this figure here, this net shows two bases right here and here. So, this has two bases and it has six rectangular faces such as this right here. Now, when this net is folded along the edges, it forms a 3S figure and this figure is called a hexagonal prism. All right, remember that a net is a pattern made when the surface of a 3D figure or three-dimensional figure is laid out flat showing each face of the figure. A net is folded to make a three-dimensional figure. Remember that a figure can be unfolded in more than one ways. Always remember to identify the base. Identify the base of the net and fold along the edges to form the respected 3D model.
