  1. The great pyramid OF EGYPT: A lesson in conversionsBy: ShantÉ, Amber and Chinco

  2. 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. • 1yd=3ft 481/3=160.3yds • In comparison the great pyramid is 60.3 yds. higher than the football field is in length .

  3. Volume Of The Great Pyramid • 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.

  4. How Many Stone Blocks do You Think Were Used? • 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.

  5. How Long Did It Take To Build 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.

  6. How Does The Volume Of The Eiffel Tower Compare? • 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.
