Question

Is ice cream cone a 2D or 3D object?
A. 2D
B. 3D
C. Does not exist in both the planes
D. None of these

Answer 1

Hint: In this question, we have been asked whether ice cream cones are 2D or 3D. To answer this simple question, look at the properties of 2D and 3D objects. Basically, if an object has a 3rd dimension- height, then it is a 3D object. Only height is a factor in 3D objects that differentiates them from the 2D objects. Notice whether the cone has height or not.

Complete step-by-step answer:
Before moving to the question, let us understand a little about 2D and 3D figures.
2D figures- These figures are flat plane figures that have only two dimensions – a length and a breadth. These figures have no thickness and can only be drawn on pages.
3D figures- These are solid figures that have three dimensions – a length, breadth and a height. In addition to 2D figures, these figures have depth or thickness.
Now, let us look at an ice cream cone.
 

As we can see in the picture, the cone has three dimensions- a radius, slant height and a height. Also, it can hold in itself some quantity which proves that it is a 3D figure.

Option B is the correct answer.

Note: Another factor to prove that an ice cream cone is a 3D object is that we should notice that a 2D object like a square or a triangle can only be drawn on paper but they cannot be held in reality. On the other hand, a 3D object like a cube or cone can not only be drawn on a paper, but can also be held in hands in reality.
