In geometry, three-dimensional shapes or 3D shapes are **bodies that have three dimensions such as length, width, and height**. Whereas 2D shapes only have two dimensions, namely length and width. Examples of three-dimensional objects can be seen in our daily life, such as E.g. a cone-shaped ice cream, a cube-shaped box, a ball etc.

3D shapes are shapes with three dimensions such as width, height and depth. An example of a 3D shape is **a prism or a sphere**. 3D shapes are multidimensional and can be physically captured.

3D shapes are **solid shapes or objects with three dimensions (length, width, and height)**, as opposed to two-dimensional objects, which only have length and width. Other important terms related to 3D geometric shapes are faces, edges, and vertices. They have depth and therefore take up a certain volume.

- Put different 3D objects in a bag or sensory tub and let your kids describe them by feel.
- Experiment to see how the different objects move.
- Continue a 3D shape hunt in the environment.

In computers, 3-D (three-dimensional or three-dimensional) describes **an image that conveys the perception of depth**. When 3-D images are made interactive to make users feel part of the scene, the experience is called virtual reality.

“**You’re used to seeing depth in objects**. This is everyday life to which they are accustomed. (And so) we need to teach them 3D understanding before we move on to 2D.” In fact, creating the right foundation for understanding geometry starts with teaching students spatial awareness, Bobo said.

Learning their shapes **also helps children understand how to put different letters together into words and simple sentences**. Once you explain 3D shapes to your students, they can build on their knowledge while developing important math skills.

2D shapes have areas but no volume. Straight lines form the sides of the 2D shapes. 2D shapes are drawn with X-axes and Y-axes. 3D Shapes: 3D stands for “Three Dimensional”. 3D shapes have three dimensions – length, width, and height or depth.

3D objects include **sphere, cube, box, pyramid, cone, prism, cylinder**.

**2D (two-dimensional) shapes are flat, while 3D (three-dimensional) shapes are solid objects with length, width, and depth**.

The three important properties of 3D shapes are **faces, edges and vertices**. The face is called the flat surface of the body, the edge is called the line segment where two faces meet, and the vertex is the point where two edges meet.

It goes like this: “3D shapes are **solid, not flat.** **They have corners, edges and faces**. What do you think of that?” Using the chant was a quick way to introduce and review vocabulary: solid, flat, corners, faces, and edges.

Examples of 3D shapes

**Cube – Cube**. Shoebox – Cuboid or rectangular prism. Ice Cream Cone – Cone. Globe – Sphere.
