# How dense would an object have to be in order to hold up a makeshift earth.

Tirent
I know that this may be very odd,but I wanted to calculate the density of the pillar of the world from the God of War franchise.This pillar by itself as small as it is is able to hold the Earth up quite easily. So i just wanted to have an estimation of how dense an object like a pillar would have to be in order to hold up an Earth sized planet with the same weight of earth.

Let's just factor these in and just assume that

>The gravity is the same as earth's
> The pillar is 1000m in height and has a 4x4 base so a side would be about 100m
>The pillar is on top of a stable flat surface.
>The pillar is a rectangular prism.

Also just a quick question,which of the following could successfully hold up this fake Earth without being crumbled?

1.A sky scraper
2.10 sky scrapers
3.A Mountain of 1000 meters
4.Mount Olympus
5.All of the mountains in the Earth put together into one giant mountain
6.an island separated from the water that is about the size of Jamaica
7.The same as above but the island is the size of Texas
8.A continent ripped from earth(Africa)
9.multiple Africas(3)
10.A moon

Or simply can you just tell me how much something would have to weigh in order to hold this fake Earth up.
