# Dimensions of the Egyptian pyramids

When we look at the three main pyramids of the Giza plateau, we are surprised to see that Khafra is higher than Khufu, despite the fact that we learned the opposite ... In fact, it is a optical illusion because the pyramid of Khafra is on a raised rocky base which makes it seem higher than it really is, but if we measure them, we see that it is that of Khufu, his father, which is the highest.

That of Menkaure, it is smaller, like the other pyramids of Egypt.

When we want to know the dimensions of a historic building, we must ask the question of the unit of measure, because if today the meter is almost universally admitted, at the time of ancient Egypt the population measured in royal cubits, the length of which varies slightly in time but which is between 0.5 and 0.6m. The dimensions of the pyramids are therefore, for the most part, multiples of one cubit.

Here is the list of some of these pyramids with their dimensions.

## Pyramid of Khufu

Pyramid of Khufu

The pyramid of Khufu is the largest of all the pyramids of Egypt. It is the highest, but also the largest and the one with the largest volume. It has long remained the largest structure ever built by man.

 Characteristics Measures Initial height 146,60 m Actual height 138,00 m Length of the South side 230,45 m Length of the North side 230,25 m Length of the West side 230,36 m Length of the East side 230,39 m Floor area 5,29 ha Base horizontality Difference of 21 mm Volume 2 592 350m3 Area 53 055 m2 Tilt 51°50'34", a height / width ratio of 14/11e Measure the Northeast angle 90° 3' 2" Measure the North-West angle 89° 59' 58" Southeast angle measurement 89° 56' 27" Measuring the Southwest angle 90° 0' 33"

The length of each side is, to a few centimeters, identical. This is not insignificant since it corresponds to 400 cubits, a unit of length in progress at the time of ancient Egypt. A royal cubit was 0.577m at that time, which is confirmed by the height of the pyramid, 147m, 280 cubits. In ancient Egyptian measure, the pyramid is therefore 400 cubits per side by 280 high.

Mathematically there is a relationship between the length of the base and the height of one side: 1.25, a ratio perfectly mastered by the manufacturers, of course.

## Pyramid of Khafra

Pyramid of Khafra

Wider than the pyramid of Khufu but lower and less voluminous, the pyramid of Khafra has in common with that of Menkaure to have retained some of the coating of which it was adorned formerly.

 Characteristics Measures Initial height 143,87 m Actual height 136,40 m Length of one side 215,16 m Volume 2 211 096m3 Tilt 53°07'48", a height / width ratio of 4/3rd

## Pyramid of Menkaure

Pyramid of Menkaure

The smaller pyramid of Giza does not have a very square base, it is very slightly rectangular. Much smaller than the other two since they are 2.5 times its height, it is especially nearly 10 times less bulky!

 Characteristics Measures Height at the origin 66 m Current height 65,5 m Length of the sides 104,6 m and 102.2 m Volume 235 183m3 Tilt 51°20'00''

## Pyramid of Djoser

Pyramid of Djoser

Djoser was a Pharaoh of the Third Dynasty. His tomb is remarkable in that it is a link between the royal burials of the first dynasties, the mastabas, and the monumental ones of the Fourth Dynasty, on the Giza plateau. It is a step pyramid which is actually a succession of improvements to the mastaba to be used as burial.

 Characteristics Measures Initial height 62 m Lenght of one side 125,27m and 109,12m Volume 330 4003 Tilt 84°, chaque degré
