### Building a Pyramid

I promised my little brothers that I would put some pictures of the pyramid I built in Minecraft up on my blog, so here they are.

 View of the pyramid from the south, along the entrance causeway.
This pyramid was actually a pretty interesting learning experience. Minecraft takes place in a world of blocks, which are usually taken to be one meter on a side. When I decided to build a pyramid, I first thought of building a replica of the Great Pyramid of Giza, which is 230.4 meters (755.9 feet) on a side at the base and would have stood 146.5 meters (480.6 feet) tall when it was built. Given the constrictions of Minecraft my pyramid would need to have a 45$$^\circ$$ angle rather than the 51$$^\circ$$ 50' 40" of the actual one (and thus only 115 meters high), and a quick calculation showed that it would require on the order of 2,054,360 blocks to build an entire pyramid.

Edit (6/14/13): The calculation is simple; it's just
$N=\sum_{n=1}^{115}(2n)^2$ which can be solved in four lines of Python code, viz:
>>> N = 0
>>> for n in range(1, 116):
...    N += (2 * n)**2
>>> print(N)

I also quickly learned that the area I wanted to build it in was much too small, so I decided to scale down and build a smaller pyramid 100 meters on a side. The same calculation showed that such a pyramid would still require 171,700 blocks (same calculation as before with different upper limit), and since I was going to have to gather every single block myself, I decided to cheat and take advantage of Minecraft physics (or lack thereof) to build a hollow pyramid consisting of only an outer shell.

This scheme still required a total of 10,000 blocks of sandstone, which I methodically went about gathering. (Edit (6/14/13): To arrive at that number, imagine the pyramid as a series of concentric square rings, since it's hollow. You can imagine collapsing them down into each other, until you have nothing but a square patch of sandstone a hundred meters on a side. Simply square that number, and you arrive at 10,000.) The entire process of gathering materials and building the pyramid probably took me a good ten hours over a period of several days, and really put into perspective what it must have taken to build an actual, solid pyramid over twice as large as the one I finally completed.

1. Oh, ha ha! Nice.

1. Dan,
I have done a similar project in Minecraft and came to the same conclusion as you of using a hollow design. I used torches to flatten the base of excess sand and also to designate the base. An odd number of blocks was needed for the sides so the pyramid came to a squared off point. Using sandstone blocks (many made from the excess sand) I made the overall structure, then added sandstone stairs for the sides and half blocks for the corner edges. I came up with a system whereby I added a sandstone block at the corner of each square level to act as a key for the next highest level.
For the top I used a gold block below a glowstone block. I wish they had a pyramidion shape in Minecraft, and even slanted blocks for the facing blocks. Something like snow would be ideal to emulate the white stone used on the real pyramids, and gold for the pyramidion.

I have since added a temple (with garden and sacred pools) and a stadium. My Egyptian district continues to expand. I had fun doing this project and it is nice to see that your efforts and solutions were similar to mine. My background is in Egyptology and I enjoy doing hands-on simulations of Egyptian architecture, admittedly one of the longest lasting, so they must have done something right!

Take care,

1. Thanks for the comment! I came up with the exact same system of adding a block at one corner to use as the foundation for the next level. I wish I'd thought of gold for the top (and I share your wish for an actual pyramidion shape), I think I just had a lot of obsidian on hand and thought that the black/purple color would be a nice contrast.

I'm afraid I have no background in Egyptology other than a layman's knowledge, but I do find it a fascinating subject!

Think I said something interesting or insightful? Let me know what you thought! Or even just drop in and say "hi" once in a while - I always enjoy reading comments.
