It took 14 years to build Mount Rushmore.:)
It took 5 years to build.
It is estimated that construction took between 14 and 20 years, around 2560 BC.
Depends on the size of the pyramid. The Great Pyramid of Pharaoh Khufu at Giza is said to had taken 14 to 20 years to build.
It Took 14 Years
it took 30-40 years to build a pyramid
the great pyramid of Pharaoh Khufu for example, took 100,000 slaves and 20 years to do it20-30 years to make the Egyptian pyramids.20 or more years
it took about 20-30 years
It took about 30 or 40 years....If more!
it would take around half an hour to cross with 105km
The Erie Canal took 8 years. It took ten years to build the Panama Canal.
No, it took about two years to build.
it took three years for the titanic to be constructed
It took 15 years to build the Parthenon. However it took 22,000 tons of marble to build it, not 20,000. Main answer = Parthenon
It took 14 years to build Mount Rushmore.:)
Answer 30 years There is a mathematical problem with the above 30 year answer. If you do the math there are 10,950 days in 30 years. If there are 2,300,000 blocks in the largest pyramid, that would be putting in 210 2 1/2 ton blocks a day! I don't think that rate is possible. That doesn't take into account the time to get the site ready and start up the construction. So, they it may have taken 30 years, but I don't think there can be that many blocks in the pyramid. I would guess the estimate of the number of blocks is too large. The internal structure must be different then is what is currently believed to be. If we find out the complete details of the internal structure, we might finally find out how they were built. I think you are both wrong the answer is 24 years Well i think sorry i know it took 50 years to build the great pyramid of Giza because they used 2,000,000 milloin limestone blocks so th maximum amount would be 20-50 years to build 1 pyramid.
