00:00For 4,500 years, the Great Pyramid of Giza has been this absolute engineering marvel.
00:05It's a puzzle that even today still kind of messes with our heads.
00:09I mean, we've walked on the moon, we've built skyscrapers that literally pierce the clouds,
00:12but this ancient wonder, it still holds secrets that baffle the world's best engineers.
00:17So let's explore what it would actually take to build it today.
00:20It's a simple question, right?
00:23But the answer is startlingly complex.
00:25You'd think, with all our technology, sure, no problem.
00:28But the reality of recreating this ancient megastructure is so much more daunting,
00:32and frankly, so much more expensive than you could possibly imagine.
00:37Okay, to really wrap your head around the scale here, let's just put it in perspective.
00:41The Great Pyramid is made of 6 million tons of stone.
00:45That is 12 times the weight of the Burj Khalifa, the tallest building on the entire planet.
00:50We are talking about a man-made mountain as tall as a 40-story building
00:54and covering an area the size of 10 football fields.
00:56It's just immense.
00:57So, the big spoiler.
01:00Could we actually do it?
01:01The surprising answer is probably no.
01:04And you know the craziest part?
01:05The biggest hurdle isn't a lack of cranes or cutting-edge tools.
01:09It's a lack of purpose.
01:11The ancient Egyptians built these incredible structures as tombs for their pharaohs,
01:15who they saw as god-kings.
01:17They had this powerful, unifying religious motivation.
01:20We, well, we just don't have that.
01:23But hey, for the sake of this explainer, let's pretend we've found a reason.
01:27Let's build this thing.
01:29All right, now we get to the fun part, our hypothetical project.
01:33We've got our motivation.
01:34So, what's step one?
01:36You might think it's quarrying stone, but nope.
01:38First, you have to build a foundation strong enough to hold a literal mountain.
01:43And this phase alone, it's going to take three years.
01:47You know, the ancient Egyptians actually learned the importance of a good foundation the hard way.
01:52The famous Bent Pyramid, it started to subside because it was built on unstable ground.
01:56To avoid that same mistake, we'd need extensive geological scans, seismic tests.
02:01And then, we'd have to laser level the entire 13-acre site with millimeter precision.
02:06Why?
02:07Because a single millimeter of error at the base would create a nearly 15-centimeter lean at the top.
02:12A huge deal.
02:13So, after buying the land, you'd have to pour this massive, reinforced concrete foundation.
02:19And we're not talking about just a simple slab.
02:21We are talking about half a million tons of concrete.
02:25I mean, some entire modern mega-projects don't even use that much material.
02:29And for us, it's just the starting point.
02:32So, let's do a quick tally.
02:34We are three years into this project.
02:36We're already over half a billion dollars in the hole.
02:39And we haven't even thought about touching the first stone block yet.
02:42Not one.
02:43All right.
02:44With the site finally prepped, we move on to the next colossal challenge.
02:48Querying and cutting 2.3 million stone blocks.
02:52Most of which, by the way, are the size of an SUV.
02:55This chart really gives you a sense of the mind-boggling industrial scale we need here.
03:01A single modern stone cutting factory working at full capacity would need 63 years to produce all the blocks.
03:08So, to hit our much more reasonable five-year target for this phase,
03:12we would need 250 industrial-grade diamond wire saws running all at the same time, right there at the quarry.
03:19Now, the cost of the raw materials, it's just staggering.
03:24The stone alone, both the limestone and the granite for the inner chambers, would cost around $1 billion.
03:30To put that in context, the entire Burj Khalifa was built for $1.5 billion.
03:35And the electricity to run those 250 saws for five years?
03:39About $155 million.
03:41Which, get this, is equivalent to the entire country of Italy's electricity consumption for one full day.
03:48Time to update our running total.
03:50We've just added over a billion dollars to the bill, bringing us to $1.7 billion.
03:56The cost has now tripled, and we still haven't moved a single block to the construction site.
04:01Okay, so the blocks are all cut.
04:03Now we have to get them from the quarry in Oswan to our site in Giza, a journey of 900
04:08kilometers.
04:09This would be, without a doubt, the largest transport operation in human history.
04:14First off, just let that number sink in.
04:17Six million tons.
04:19How do you even begin to move that much weight across an entire country?
04:23Well, let's break it down.
04:24If we use standard heavy-duty trucks that can carry about 25 tons each,
04:28we would need nearly a quarter of a million individual truckloads to deliver all that stone.
04:33240,000 trips.
04:35Imagine it.
04:36A constant, unbroken convoy of 500 trucks,
04:40driving day and night for five straight years.
04:44Every 10 minutes, another truck would arrive at the construction site.
04:47The logistical coordination would be an absolute nightmare.
04:51And the price tag for this five-year-long convoy?
04:54A cool $200 million.
04:56That brings our new total to just over $1.9 billion.
05:01And incredibly, that doesn't even include things like road taxes.
05:04So, after all that work, the materials are finally on site.
05:09The challenge now shifts from pure logistics to pure, hardcore engineering.
05:13We are now entering the most complex, and honestly, the most dangerous phase of the entire project.
05:19The actual construction.
05:21This right here is the ultimate engineering challenge.
05:24The granite blocks that make up the roof of the king's chamber weigh up to 80 tons apiece.
05:30The problem is, no single crane on Earth has both the height to reach the top of the pyramid
05:34and the strength to lift 80 tons at that height.
05:38Physics just gets in the way.
05:39The solution would require a complex, custom-built network of the world's largest tower cranes,
05:44all choreographed in a series of tandem lifts.
05:47They would literally have to build their own foundations on the pyramid's lower levels,
05:51get disassembled, and then raised higher as the pyramid itself grew.
05:54It's an unprecedented and incredibly risky operation.
05:57Just renting, operating, and maintaining this specialized network of cranes for five years
06:03would cost at least $300 million.
06:06And then there's the human element.
06:08A project of this scale would require a crew of at least 3,000 people.
06:12And we're not talking about just general laborers.
06:15We're talking elite crane operators, engineers, surveyors, and safety coordinators,
06:20all working in a super high-risk environment.
06:22Their salaries, insurance, and provisions over five years would add another $400 million to the bill.
06:30We are almost there.
06:32After eight years of planning and construction, our pyramid stands tall,
06:36looking a lot like it does today.
06:38But to truly replicate the original, there's one final dazzling step.
06:43See, the Great Pyramid wasn't originally the sandy brown color we see now.
06:47It was encased in 115,000 blocks of highly polished, brilliant white limestone from a place called Tura.
06:52This casing made the entire structure smooth and flat,
06:56causing it to just gleam in the sun and shine like a beacon in the moonlight.
06:59Adding this incredible finishing touch would cost another $250 million.
07:04And here it is.
07:06The final bill for our modern Great Pyramid comes to just under $3 billion.
07:10That's the same price tag as modern marvels like SoFi Stadium in Los Angeles,
07:15or one of Qatar's largest natural gas processing plants.
07:18Which brings us right back to our original question.
07:21Can it be done?
07:23Well, technically yes.
07:25But practically and financially, absolutely not.
07:29In our modern world, what government or corporation could possibly justify spending $3 billion on a project
07:35with zero financial return, no economic output?
07:39It's just unthinkable.
07:41And maybe that's the real lesson here.
07:44As the famous Egyptologist Zahi Hawa said,
07:47Egypt didn't build the pyramids.
07:48The pyramids built Egypt.
07:50The true achievement wasn't just the final structure,
07:52but the organization, the technology,
07:55and the unified society that had to be forged to make it possible.
07:58It was a project that built a nation.
08:01Which leaves us with a pretty big question.
08:03What could we build if we had a purpose that grand today?
