表面积

表面积是指一立体图形所有面的面积之和，或者用纸做成那个立体图形，所需要的纸的面积。

a为边长，r为半径，h为高

  • 正方体

S=6a^2

  • 长方体

S=2\left(a_1a_2+a_2a_3+a_3a_1\right)

  • 圆柱体

S=2\pi r^2+2\pi r h（底面积+侧面积）

  • 圆锥体

S=\pi r^2+\frac{1}{2}\sqrt{r^2+h^2}\times2\pi r = \pi r(r+a)（底+扇形：S=\frac{1}{2}×圆周×弧长）

  • 球体

Surface area 表面积

A cone, sphere and cylinder of radius r and height h.
The inner membrane of the mitochondrion has a large surface area due to infoldings, allowing higher rates of cellular respiration (electron micrograph).

The surface area of a solid object is a measure of the total area that the surface of the object occupies. The mathematical definition of surface area in the presence of curved surfaces is considerably more involved than the definition of arc length of one-dimensional curves, or of the surface area for polyhedra (i.e., objects with flat polygonal faces), for which the surface area is the sum of the areas of its faces. Smooth surfaces, such as a sphere, are assigned surface area using their representation as parametric surfaces. This definition of surface area is based on methods of infinitesimal calculus and involves partial derivatives and double integration.
