Question

Tell the students that shapes which have length, breadth, as well as thickness or depth, are called three-dimensional models.

Answer 1

Understanding 3D Models

1. Definition: Explain that 3D models have length, width, and depth, unlike flat 2D shapes.
2. Examples:
   1. Cube (e.g., dice)
   2. Sphere (e.g., ball)
   3. Cylinder (e.g., can)
   4. Cone (e.g., ice-cream cone)
   5. Cuboid (e.g., box)

Here's an illustration of common 3D models.
