Hi,

I do not know how to solve this problem, I think I used the wrong equation.

(a) How much gravitational potential energy (in ]) (relative to the ground on which it is built) is stored in an Egyptian pyramid, given its mass is about 9 x 10*kg and its center of mass is 38.0 m above the surrounding ground? (Enter a number.) (b) What is the ratio of this energy to the daily food intake of a person (1.2 x 10' ])? (Enter your answer as a ratio to the number 1. Enter a number.) :1
