The Great Pyramid of Egypt

VIEWS: 7 PAGES: 6

									   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.
