What are 3D shapes? Ever wonder what art is without shapes? Surely, it is something we cannot fathom. With art, it comes with shapes. Whether we draw buildings, nature, people, or other pieces, shapes have always been there and are an integral part of what art is. Whether a square, circle, triangle, or rectangle, every art piece will always have a shape. All of these shapes are considered 2d shapes, but we all know there is more to them. Shapes that have length, width, and height are called 3D shapes.
Now, if you have a child interested in art and looking for a way to teach them about 3-D shapes, you’ve come to the right post. Here we guide you with information as to how you can explain what a 3D shape is.
To answer the question, “What is 3d shape?”, 3D shapes are three-dimensional shapes and object that is different from 2D shapes. These are shapes that have height, width, and length. It has thickness and depth. In short, these shapes are not flat—a part of the geometric shapes we see daily.
Properties of 3D Shapes
To explain more, 3D shapes have properties that set them apart from other shapes. You should remember these properties to identify if a particular shape is 2D or 3D. Below are the following properties.
Each 3D shapes have a face. Faces refer to any flat surface or curved surfaces that can be seen in the shape. Think of a box. If you are going to count the sides of the box, you’ll going to see that it has six sides. These sides are referred to as faces.
Now that you’ve learned what a face is let’s go to the second property, the edge. To put it simply, an edge is where two faces meet together. Just look at the box and try to find the part where the faces meet.
The third and last property of a 3D shape is the vertices. It refers to the pointy part where the edges meet. Often edges and vertices interchange. Imagine you are walking, and your toe hits the pointy part of the cabinet. We usually say that we hit the edge, but it is the vertices in geometry.
Different 3D Shapes
Now that you’ve learned the different properties of 3D shapes let us meet them individually.
1. Sphere is the most common example of a 3D shape. You might be wondering where are the edges of the sphere. There is none. The sphere has zero edges and vertex, but it has a continuous face, allowing it to be a 3Dshape. The perfect example of it is a ball.
2. Cube. I know you’re familiar with a Rubik’s cube. It is a very example of a cube. It has 6 faces of a square, 12 edges, and 8 vertices.
3. Pyramid. Yes, the famous pyramid of Egypt is considered a 3D shape. It has 5 faces, 8 edges, and 5 vertices.
4. Cylinder. is a 3D shape with 2 flat surface at the top and the bottom and a continuing surface that is curved. It has 3 faces, 2 edges and 0 vertex.
5. Cone. Think of an ice cream cone. It has 2 faces, 1 edge, and 1 vertex. You might be wondering where are the faces on this shape. The first face is a circular shape at the bottom. The second shape is tringle making the cone.
6. Cuboid. The cylinder has 3 faces. The top and bottom shapes are considered the face, making it two. The third face is the curved body of the shape. It has 2 edges but does not meet, so it has no vertices.
7. Torus. It is like a donut. 2 oval shapes put together and connected with a hole at the center. Similar to a circle, it does not have edges and a vertex but has 1 surface.

Facts About 3D Shapes
Now that you’ve learned about the basics of a 3D shape, here are some interesting facts you can read to add some knowledge.
- Traffic cones are examples of Cones.
- Euclid is the father of geometry.
- Vertices are the plural form of the vertex.
- The perfect example of a cylinder is a soda can.
- The space that a 3d shape occupies is called volume.
- The rhombicosidodecahedron is the largest 3D shape in the world. It has faces of 20 triangles, 30 squares, 12 pentagons, 60 vertices, and 120 edges.
Now that you’ve learned what 3D shapes are, surely you’ll be able to explain this to your child and explore these shapes and turn them into a magnificent piece. You see, these shapes can be found around us. Probably before, you’ll just interact like nothing, but now that you’ve learned it, surely you and your child will see the world differently like you’ve never seen before.
