The length of the professional football field
(without the end zones) is 100 yards, and the
height of the great pyramid is 481ft.
1yd=3ft
481/3=160.3yds
In comparison the great pyramid is 60.3 yds.
higher than the football field is in length .

V=(1/3)x (area of the base) x height.
(1/3 )x( 756)^2 x 481=91,636,272 cubic ft
1 cubic yard = 27 cubic feet
91,636,272/27=3,393,936 cubic yards.

1 stone = 1.5 cubic yards
3,393,936/1.5=2,262,624
In this pyramid 2,262,624 limestone blocks
were used to construct the great pyramid.

Based on a University of Chicago Study:
1 stone = 2.5 minutes
2,262,624 x 2.5 = 5,656,560 minutes
1 hour = 60 minutes
5,656,560/60 = 94,276 hrs
12 hours = 1 working day
94,276hrs/12 = 78,563 12-hour work days
365 days = 1 year
7,856.3/365 = 21.5 years
It took approximately 22 years to build the great
pyramid.

V=(1/3) x (area of the base) x height
V= (1/3) (120)^2 x 980 = 4,704,000 cubic feet
The Great Pyramid with volume 91,636,272
cubic feet is greater in size than the Eiffel
Tower with volume 4,704,000 cubic feet.
