Question 272273
The Great Pyramid of Egypt, the burial tomb of King Cheops has a square base.
 It is 481.4 ft. tall and has a volume of 91,000,000 cubic feet.
 Find the length of it's base in feet.
:
Let x = the side of the base (which is square)
:
481.4*x^2 = 91000000
x^2 = {{{91000000/481.4}}}
x^2 = 189031.99
x = {{{sqrt(189031.99)}}}
x = 434.778 ft
