Here it goes:

the great pyramid of cheops is 410 feet tall and 755 feet square at the base. find the volume of the pyramid using calculus.

Part two:

The stone used in constructing it has a density of 200lb/ft^3. Find the work against gravity in building the pyramid.

I understand you integrate from 0 to 410 of the volume of each slab with a thickness of deltaX(or would it be delta y?) I am unsure how to calculate part two though, i haven't had much experience with work and force. anyone want to drop a hint or two
