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.
