Exploring 3D Shapes
What Are 3D Shapes?
3D shapes are solid figures that have length, width, and height. They take up space and can be seen all around us!
Common 3D Shapes
- Cube: All sides are equal squares (like dice)
- Rectangular Prism: Like a box or a brick
- Sphere: Perfectly round, like a ball
- Cylinder: Like a can of soup
- Pyramid: Like the pyramids in Egypt
Faces, Edges, and Vertices
- Faces: Flat surfaces on a 3D shape
- Edges: Where two faces meet
- Vertices: Corners where edges meet
Why Are 3D Shapes Important?
Understanding 3D shapes helps us build, pack, and organize things in real life!
Real-World Uses
- Packing a lunchbox with different-shaped containers
- Building a sandcastle with buckets of different shapes
Examples
Stacking cubes to build a tower.
Rolling a ball (sphere) across the playground.
In a Nutshell
3D shapes have length, width, and height and are everywhere around us.
