Properties of 2D and 3D Shapes

The video tutorial introduces solid shapes, also known as 3D shapes, which have three dimensions: length, breadth, and height. Examples include cubes, cuboids, cylinders, cones, spheres, and pyramids. Each shape has unique characteristics such as faces, edges, and vertices. The tutorial also briefly covers 2D shapes, which have two dimensions: length and breadth.

What is a characteristic of solid shapes?

• They have no volume.

• They occupy space.

• They are flat.

• They have two dimensions.

Which of the following is NOT a 3D shape?
