It has 12 faces, and all are like pentagons.Ī triangular Prism is a prism having two triangular faces whose vertices are connected by an edge forming a rectangular face. A regular polyhedron is a 3D shape having all faces of the same shape.Ī dodecagon is also called a regular polyhedron whose all faces are of the same shape. It has six edges, four faces, and four vertices, respectively.Ī square pyramid is a pyramid that has a square base, and the rest faces are like triangles together connected at a single vertice at the tip.Ī sphere is a Rounded Solid ball that does not contain any flat surface and edges and verticesĪ polyhedron is a solid and 3D shape that contains flat surfaces and straight edges. The cut surface looks like a circle, and the other portion is like a solid semicircle.Ī pyramid with all faces like a triangle is called a tetrahedron. $2.A hemisphere looks like a cut portion of the sphere. The 3d shapes set pictured below is available in my shop. These 3-d geometric shapes would be fun hanging up by a string as a decoration, too! To fold this up, you just start folding the triangles and it sort of just bends into the shape. You could probably fit a 2.5 inch one on a paper. The 3d octahedron I made 2 inches per side, but it ended up very small. Six of them are in a row facing opposite directions The other two are hanging off the ends. It is a series of 8 equilateral triangles. How to Make a 3d Octahedron: The octahedron was the trickiest. I made this by cutting into the other parts and removing the sections. Then one of the sections needs a square cut-out. How to Make a 3d Cuboid: For the cuboid, I divided the paper into fourths. You have to make sure each side of the triangle is equal to the sides of the square. How to Make a 3d Square Based Pyramid: A Square-based Pyramid is started with a square and then triangles coming out from each side. It ended up being 2 3/4 of an inch per side. I measured the sides of my paper sections to make the triangle side the same length. How to Make a 3d Triangular Prism: The Triangular Prism is made by dividing the paper into thirds. Then in the center section you will make your triangular cut-outs. You need four squares going down and three going across. How to Make a 3d Cube: For the 3d cube, you need a cross-like shape with even squares. Wrap it up and add a piece of tape to secure it. How to Make a 3d Cone: For the cone, I traced a large circle, then cut a wedge out of the circle. To make each of these 3d shapes I used an 8 1/2 x 11 sheet of paper to make them. There are 6 common 3d shapes that I am going to teach you about today. I also have printable templates with a few more 3D geometric shapes, if you want a simpler way to make them! They are available in my shop. They were pretty fascinated by it all.Īll you need to make these paper 3d shapes is paper, scissors, a pencil, a ruler and tape. Then they tried making lots of other kinds of shapes out of paper. They played around with them for a while. Learning to makes these shapes would be great for geometry or just to practice the 3d shapes names. Plus I also have printable templates available for you. Today I want to share with you how we made 6 different 3D shapes out of paper. I think it is so neat that from just a piece of paper you can make so many different things. I have always been fascinated with origami and other paper folding crafts. Let’s make 3d Shapes with paper! It’s easier than you may think.
