Is it possible to build a wall around France?


We must first calculate the number of stones in the pyramids. Although there is little free space inside the pyramids were used for the burial of Pharaoh and his baggage, but they were very small compared to the total size. Let us assume that the pyramid was solid and hollow.
Equivalent volume of the pyramid is the

V = 1 / 3 * H * Ab

Where h is the size of the pyramid, t is the rise, with a base area. If we start Boukovo, as the base of 230 square meters of hand, and an area of 52.900 square meters. And height of 146 meters. If:

H = 1 / 3 × 146 × 52.900 = 2574467 m 3.

Following the same steps, we will find that the volume of Khafre = 2203392 m 3 and the size of Menkaure = 256 605 m 3, and the total volumes of the three pyramids = 5,034,467 m 3.
Now consider the wall of Napoleon's supposed to, how much will need to build 1 km of the fence? The size will equal length × width × height, length 1 km, ie, 1000 meters. And height of 3 meters and width 30 cm, or 0.3 meters. If:

Ie: h = 1000 × 3 × 03 = 900 m 3

So every 900 m 3 of stones will build a wall length of 1 km 3. And dividing the total size of the Al-Ahram on the size of the stones such a distance, such as building size of the stones enough to build
5594 km, is this enough to build a fence around the entire France? Is this enough to take all state?

The red square on this map of side length 1000 km, then milieu of France = 4000 km, which means that there are 1594 km of rock excess.
But it will probably not what was going on the mind of Napoleon. Maybe he meant to take the beach and the border fence and the neighboring countries? Is it sufficient stones then? We can not answer, this is strange, because the length of the border depends on the type and length of the ruler that we use. Whenever we use a ruler would be smaller cm greater.
