椭圆内接定边长三角形的面积最大值

The volume of a cube is the cube of its side-length.

立方体的容积就是它的边长的立方.

It was a satisfyingly hunky sort of thing: a box with a square top about the length of her forearm on each side, and about the length of her hand deep, wrapped up in brown plasper with an ingenious new form of self-knotting string.

这是个挺叫人满意的大块头：正方形的盒顶，边长大概跟她的上臂相当，有她手掌的长度，用棕色的有机材料包裹着，还带着新型的自动绳结，非常精巧。

To calculate the area of a square double the length of one side.

要计算正方形的面积,只需用边长自乘即可.

In order to analyzing the vehicle-track coupling vibration character of infinite length track, a time-varying model of railway tangent track spatial vibration was presented. This paper gives out states, feature and causes of alternately rail side attrition in the straight line intervals of railway.
