There is no way to know exactly how long it took to build the Egyptian pyramids. Herodotus was told that the Great Pyramid at Giza was built in twenty years; however, scientists today claim it could have been built in as few as ten years.
If it is a 4 faced tetrahedron pyramid then its complete surface area is 4*80 =320 square centimetres
66m tall and 247 weight
Depends on the pyramid. The step pyramid of Djoser has blocks weighing on average about 500kg. By the time of Khufu (2589-66 BCE) the average weigh of a stone used on his Great Pyramid was about 2,550kg ( approx. 2.55 metric tonnes, 2.5 long tons or 2.8 short tons)
In geometry, pyramid has many forms such as rectangular pyramid, trapezoidal pyramid, quadrilateral pyramid and even triangular pyramid. Triangular pyramid is a pyramid with triangular base and can be called as a tetrahedron if each of its faces has congruent equilateral triangles.
A square pyramid is a pyramid whose base is in the shape of a square.
