Question

Which of the following is a 3D object?

• A. Paper
• B. Geometry box
• C. Water bottle
• D. A sharp blade

Answer 1

Answer: (B), (C)

The correct options are
B Geometry box
C Water bottle

A 3D object is defined by three measurements: its length, breadth, and depth (or height).

• A paper and a sharp blade do not have depth or height, so they are not 3D objects.
• A geometry box and a water bottle has length, breadth, and height as well. So, they can be called as 3D objects.
