Question

What is a key difference between 2-dimensional and 3-dimensional shapes?

Options

• 3D shapes have only length and breadth

• 2D shapes have length, breadth, and height while 3D shapes have only length and breadth

• 2D shapes have only length and breadth while 3D shapes have length, breadth, height, or depth

• 3D shapes cannot be measured

Answer 1

2D shapes have only length and breadth while 3D shapes have length, breadth, height, or depth

Explanation:

Two-dimensional shapes (plane figures) have only length and breadth, while three-dimensional shapes (solid objects) have three measurements: length, breadth, and height or depth.
