Hey guys, today we are going to look at the mysterious Angkor Wat Temple in Cambodia, which has many strange secrets hidden inside. Historians say it was built about 900 years ago with simple tools , but by the end of this video, I think you will agree with me that this is not true at all. You may have already known that this is the largest religious monument in the world, but how big is this temple? The temple stretches more than 400 acres, that is more than three times the size of the entire Vatican city, or about 300 times the size of an American football field. So you can imagine the size of this temple. Even if we take out all the walking space and empty land, the sheer area covered by stone blocks is at least 10 Million Square Feet. And we are not looking at just a 2 dimensional ground area, we have to look at the volume in 3D because it is made of layers and layers of stone blocks, pillars, ceiling, and towers. The Iconic central towers in the middle, which almost look like drill bits, they are still the tallest structures in this city, even after all these years. The central tower is 213 feet tall, and this view is actually printed on the Flag of Cambodia. So imagine what would be the sheer volume of rocks needed to build a temple which stretches for 10 million square feet and has a pyramidal height of more than 200 feet. If we calculate the weight of all the sandstone blocks which make up this pyramid, we get about 52 Million tons of rock. I have used a calculator to calculate this weight, using the density of sandstone. Now, we have already not included the rocks in the foundation, we have not included the millions of stone blocks going many feet deep in the moat, and the rocks placed around the moat. And that is already 52 Million tons of rock. Now what I am going to do is take only 20% of this number, so this way we know this is a very very conservative estimate, because Angkor Wat is not a true solid pyramid, there are lots of hollow spaces in between. Let us actually take even less than 20%, we will only take 10,000,000 tons. So this way we know at least this much of rocks would have been used to build the temple. Okay, so why are we calculating the weight of the stone blocks in this temple? Because, archeologists and historians argue that the entire temple was built in just 37 years. You know the standard theory, people using chisels and hammers to build temples. Now let us assume that these people worked from sunrise to sunset everyday for 37 years. So they worked straight for 12 hours with no breaks, they don’t eat, they don’t even blink, and no rainy days, no war, no festivals for 37 years. That is a total of 162,060 hours. So if you do the math, if you divide the amount of rocks by the number of hours, this is the answer we get, approximately 60 tons. This means that they would have to cut and place at least 60 tons of rock every hour. This is 1 Ton of rock every minute. So for every minute they have to measure, cut, carve, lift, place and align one ton of rock. This is simply IMPOSSIBLE. We cannot accomplish this even today, even with modern machinery, we have not yet developed the technology to cut, position and polish one ton of rock of every minute. That is more than 2000 pounds of rock every minute, or 1000 kilograms every minute.
