The Pyramids,Egypt
Egypt is famous for the pyramids .
Near the modern city of Cairo lies the largest and most imposing concentration of pyramids in the world, those of the Giza Plateau.
Built 4,000 years ago, the three great pyramids at Giza, in the Egyptian desert remain the most colossal1 buildings ever constructed. 矗立在埃及沙漠中吉萨的三座大金字塔建于4000年前,它们一直都是有史以来最宏大的建筑。
The structure of Pyramid
The Great Pyramid of Giza is the oldest and largest of the three pyramids in the Giza Necropolis bordering what is now El Giza, is the oldest of the Seven Wonders od the Ancient World,and the one to remain largely is 770 feet on one side and 481 feet tall.
In order to build the great pyramid, million blocks of stone were cut ,transported and assembled to create为了建造大金字塔,人们切割、运输、垒砌了大约230万块石头。
The great pyramid,also known as khufu, is 770 feet on one side and 481 feet tall .最大的金字塔——胡夫金字塔,每边长770英尺,高481英尺。
The pyramids were built by Egyptians under the orders of the Egyptian leader,whose title was Pharaoh
How ancient builders managed to build these? Nobody can answer it .But it’s sure that it needs brains and ,这一直是个未解之谜,但可以肯定的是它需要付出大量的脑力和体力。
The number puzzles of pyramid
延伸胡夫大金字塔底面正方形的纵平分线至无穷则为地球的子午线;穿过胡夫大金字塔的子午线,正好把地球上的陆地和海洋分成均匀的两半,而且塔的重心正好坐落在各大陆引力的中心。
把大金字塔底面正方形的对角线延长,恰好能将尼罗河口三角洲包括在内,而延伸正方形的纵平分线,则正好把尼罗河口三角洲平分。
,(古埃及一种度量单位),这个数字与一年中的天数相近。
()乘以10亿,约等于地球到太阳之间的距离。
大金字塔4个底边长之和,除以高度的两倍,——圆周率。
The number puzzles of pyramid
1.(金字塔)自重×l0l5=地球的重量
2.(金字塔)塔高×l0亿=
3.(金字塔)塔高平方=塔面三角形面积
4.(金字塔)底周长∶塔高=圆围∶半径
5.(金字塔)底周长x2=赤道的时分度
6.(金字塔)底周长÷(塔高×2)=圆周率(∏=.)
