It is mainly composed of a steel rectangular parallelepiped and two steel cylinders of the same diameter fixed at its two ends.

它主要由一钢制长方体和固定在其两端的两个相同直径的钢制圆柱体组成。

To the short ends of the mobile plate are fixed the parallelepiped by bolts.

对移动板块的短结束被门闩修理平行六面体。

It is made up of two parallelepiped blocks of 10x10 meters placed next to each other.

它是由两个10×10米，且彼此相邻的平行六面体组成。

The project consists of a rectangular parallelepiped building 46 metres by 9 metres set into a natural slope.

这一项目由一栋建筑在天然斜坡上的矩形的平行六面体构成，长46米，宽9米。

So, if I try to form a parallelepiped with these three sides, and P is not in the plane, then it will have some volume.

所以如果我试着用这三边构成一个平行六面体，如果点P不在这个平面内，这个平行六面体就会有体积。
