When mathematics meet with the Egyptian Pyramid

The most popular ,largest and oldest pyramids in Giza pyramid complex is known as Pyramid of Khufu. It is the oldest of the Seven Wonders of the Ancient World.

1.   The area of the slope of pyramid is almost same with the area of the square with the               length = height of pyramid.


This pyramid is such a miracle.

Egyptologists believe that the pyramid was built as tomb over a 10 to 20 year period concluding around 2560 BC.

Now, let me introduce some “magic” of mathematics in this pyramids.

Let’s consider Khufu’s Horizon as an example where its

Height = 146.6 m 

Base = 231.93 m and
The angle of slope = 51^o50’40.

                            

The area of the slanted area=21500 m²

                                      

          The length of the square = 146.6 m

By applying the formula of length = height,

The height of pyramid = 146.6m

The area of the square = (146.6)² = 21491.26 m²

Note that the slanted area is almost the same as the area of the square.

2.  The height of the pyramid times 1 million is almost same to the closest distance between              earth and sun which is 147 million km

The circumference of the base of the pyramid ( in inches) is almost the same as the number of the days in a year.

The length of the base of pyramid = 231.93 m = 9131.1023 inches

Circumference of the base of pyramid = 4 * 9131.1023

                                                                  = 36524.2092 inches

If we divided it by 100 = 365.24

This number is also equal to the number of days in a year which is 365.25 days.

Is it fantastic?

3.   And lastly you can also build your little pyramid on your own.

Height = 20 cm

Length of slope = 30 cm

Length of base = 31.6 cm

Angle between of slope and base = 52^o

Note: The pyramid must face to the direction as shown in the picture

You will find that the food you put inside the pyramid will not rot but only dehydrate.
