 If the great pyramid of giza is 463 feet tall, and one side of its square base is 770 feet, what is the slope of each face? 

Sagot :

use Pythagoras theorem to find the slope of the square pyramid
to find the slope you must image the right triangle formed
 the base of the right triangle is half the length of the base of the
pyramid
thus
   l² = h² +( b/2)²      where  l = slope
                                           h = vertical  height
                                           b = length of base
 l² =  463²+ 385²                  / 770/2 =  385
l =  √(214369 + 148225)
