For making a cube we need 12
           straws.
But for pyramid we need only 8
           straws.
Now we can check the Strength by applying
stress. Apply stress using hands on the models
we made.
The reason for this is the stress we
  applied in the pyramid is equally
 given to the sides of that pyramid.
 Thus pyramids are stronger than cubes.


   The great pyramid of Giza is the best
example for strength of pyramid. It’s built
 4000 years ago and still remains stable.
