Quote:a wall is a a great example...it has length,width and height...That is 3 dimensions you can see with your own eyes and measure all three... You can measure how tall your wall is, you can measure how long it is, and you can measure how wide it is... that is perfect example of a 3 dimensional object. when you can measure length width and height there is undeniable proof that it is 3 dimensional

 

Not saying you're wrong.  But there is still a problem.  Based on your perspective, width, height, and length are interchangeable.  In other words you could measure every dimension by holding a tape measure from your left hand to your right hand if you change your perspective.  How can you verify you are measuring a different dimension every time?
