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.
It took a different length of time for each pyramid. In the case of the Great Pyramid of Giza, it took 100,000 slaves almost 20 years to build the actual pyramid. It took another 10 years to build the causeway that connected the pyramid to the temple.
It took 20 years About 20,000 people participated most who were slaves

The Great Pyramid, which is located in Giza, Egypt, was built as a tomb for the pharaoh Khufu. He may also have been responsible for the Sphinx.
This is impossible to know, because it is not known how many men, and what engineering techniques were employed. It may have been 2,000 men or 20,000 men. It may have taken ten years or 80 years, or 150 years.
It took 13 years to build the Brooklyn Bridge. Construction began in December 1869 or January 1870, and the bridge opened on May 24, 1883.

Time It takes To Build Peaking Power PlantIt typically takes one to three years to build a gas turbine power plant depending on the size and complexity. A 100 MW conventional gas turbine may take about a year. A 300 MW combined cycle power plant may take about two to three years. These estimates may increase if demand for gas turbines is high.
It took around 20 years to build the largest Egyptian pyramid, (the Great Pyramid of Giza)From wikipedia:The Great Pyramid of Giza (also called the Pyramid of King Khufu' and Pyramid of Cheops) is the oldest and largest of the three pyramids in the Giza Necropolis bordering what is now El Giza, Egypt, and is the only one of the Seven Wonders of the Ancient World that survives substantially intact.

It was the tallest man made construction until the Pharos of Alexandria was build at 280 BCE.20 yearsIt took a period of 14-20 years to build the Pyramid of Khufu. ----it took more than a day and less then 21 years. he used 10,000 slaves and free men.10,000 to 20,000 naked slaves toiled in the blazing Egyptian sun for 14 to 20 years to build this symbol of vanity for a single man Pharaoh Khufu.The Pyramid of Khufu also known as The Pyramid of Cheops [his Greek name] or The Great Pyramid of Giza was built for the fourth dynasty pharaoh Khufu over a period of about 14-20 years as his tomb around 2550 B.C.See the link below.The answer is: between 14 and twenty years 14 to 20 yearsIt took 20 years. Over that period 20,000 naked slaves toiled in the blazing sun to build this symbol of absolute power and vanity.to longAbout 20 to 23 years is educationally estimated The pryamid of GizaThe great pyramid of Giza is called also called Pyramid of Khufu, It's known as the pyramid of Khufu because he built the Pyramid of Giza.

What we do know is that the 3 great pyramids of Giza were built between 2575 BC abnd 2465 BC giving a time frame of 110 to complete all 3.Egyptologists now believe that these pyramids were not constructed by slaves but will workers intent of showing devotion to the pharoah, a living god thus making sure they were would be favourably rewarded in the "After-life"It took 14 to 20 years and 100,000 naked slaves to build Khufu's pyramidIt took between 14 and 20 yearsabout twenty years
