Answer 2

91535846.6 cubic feet.

Explanation:

The volume V of a square pyramid is given by the next formula

V= l²h/3 where l is the side length and h is the height.

Substituting with h = 480.6 and l=755.9

`V=l^(2) h/3\\V=755.9^(2) (480.6)/3\\V=274607540/3\\V=91535846.6`

Therefore, this is the volume of the original Great Pyramid of Giza
