Can you slide a pyramid

Assuming you mean slide down a pyramid: You could, but not most as they were originally built with rough sides. Egyptiian classical pyramids were covered n smooth hard stone, which the idiot and very culturally primitive Napoleon took from the pyramids to use as a foundation for a causeway he built for his troops (1797?). The earlier Egyptian pyramids were known a step pyramids (mastaba) and did not have smooth sides. Other pyramids built in other countries were also not smooth sided. The Egyptian pyramids were not only therefore impressive in size and shape, but originally shown in the sun with much brilliance due to their polished stone sides.

If you mean can you slide a pyramid the answer is yes if you can get enough water under it and freeze it thus making it much easier to slide (problem, such pressure from heavy pyramids would make keeping the water under such weight/pressure very difficult.)
