Im just curious if all the water were to be above ground
if its elevation would be 400 ft above nile river elevation !!
from what I can tell an apx guess would be
1145 ft
volume of a sphere v=4/3 x (pi x r3)
v=4/3 x (pi x r^3)
700 km = 434 miles
434 miles
434 x 5280 = 2291520 ft
d=2291520 ft
r=1145760 ft
r^3 = 1504114746494976000
pi x r^3 = 4722920303994224640
4722920303994224640 / 3 = 1574306767998074880
1574306767998074880 x 4 = 6297227071992299520
v= 6297227071992299520 cu ft
surface area of the earth
a=4 x (pi x r2)
7926 miles
41849280 ft
r = 20924640
r^2 = 437840559129600
pi x r2 = 1374819355666944
4x(pi x r2)= 5499277422667776 sq ft
6297227071992299520 / 5499277422667776 = 1145.10 ft
wow , that means the earth must have been really hot back
when the pyramids were sitting almost underwater in an ocean with an elevation of 400 ft above the nile river's current elevation.
because it was already in the process of evaporating its ground water.
