如何用英语表示面积和体积

(1) 面积的表示法

This is a room 20 by 30 feet.

= This is a room 20 feet by 30.

 = This is a room 20×30 ft.

这是一个20英尺宽30英尺长的房间。

The room has an area of ten square meters.

=The area of the room is ten square meters.

 =The room is ten square meters in area.

=The room covers an area of ten square meters. 这个房间的面积为10平方米。

(2) 体积的表示法

常用“基数词+长度名词+ by +基数词+宽度名词+ by +基数词+高度名词”表示，若长、宽、高的单位一致，则通常省略后两个单位名词。如：

The box is eight inches by six by five. 这个盒子长高、宽、高分别为8英寸、6英寸、6英寸。(from www.hxen.com
