I have understood, really, and being Maths teacher I know exactly how I have to calculate it!
But it is good for what? as soon as there are data about these pyramids and you could inform there about their heights!
What s the reason of this topic?
And by the way, people visit them for their impressive looking and for their unique one in the world ! One of the seven wonders of Ancient World, not for measuring.
