It took 10 people to carry one block which was 2 tons 10 people. Now imagine you carrying around a 1 ton block with 5 kids it would look like a baby trying to pick up a big desk by him self himself :-)ha ha bla bla. Now back to the fact, these blocks were back breaking, bone crushing, neck cracking things many people died from. The strains of all of the work killed many to the hundreds to thousands. But if that's what it takes to make breathtaking artifacts then go ahead and break my back,my bones,and neck too. Ha ha just kidding that's how many people it took to build it.
