DESCRIPTIONThe great pyramid OF EGYPT: A lesson in conversions By: ShantÉ, Amber and Chinco. Comparing The Length Of A Professional Football Field. The length of the professional football field (without the end zones) is 100 yards, and the height of the great pyramid is 481ft. - PowerPoint PPT Presentation
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=160.3ydsIn 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 feet91,636,272/27=3,393,936 cubic yards.
1 stone = 1.5 cubic yards3,393,936/1.5=2,262,624In 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 minutes2,262,624 x 2.5 = 5,656,560 minutes1 hour = 60 minutes5,656,560/60 = 94,276 hrs12 hours = 1 working day94,276hrs/12 = 78,563 12-hour work days365 days = 1 year7,856.3/365 = 21.5 yearsIt took approximately 22 years to build the great pyramid.
V=(1/3) x (area of the base) x heightV= (1/3) (120)^2 x 980 = 4,704,000 cubic feetThe Great Pyramid with volume 91,636,272 cubic feet is greater in size than the Eiffel Tower with volume 4,704,000 cubic feet.
