向量方法在棱锥问题中的应用

The Application of Vector Method to Pyramid Problems

向量这一现代数学新工具引入立体几何后处理立体几何问题，有了新方法、新途径、立体几何中棱锥的侧面积、全面积、体积公式都可用向量方法给出。

With vector's(a new tool of modern mathematics) being introduced into solid geometry,there arise some new ways of dealing with solid geometry problems.The formulas of lateral area,surface area,and volume of pyramid can be given by Vector Method.
