So you took the picture 120ft away.your not very smart, just trying to troll. look at the picture 40yrds away. you see a tree that is about 16 inches in dia. running offset center. you tell me how to fake a picture so far back, it is was 4ft. the 16 inch tree in the middle would be a twig and never even show up. But, your depth and purpose isn't why most of us take a walk for stuff like this.
I love to play comparison pictures.
Here is your 40ft Pyramid.
Now here is a barn picture.
Also taken from about 120ft away.
The midway point of the peak/or the top of the granary wall is 40ft.
The knuckle of the 40ft lift is shown.
So I know what 40' was on the structure.
I think still you need to realize that your Pyramid looks like a tent in comparison.
