英语：我们一共有32个立方的货物。所以我们打算打一个20尺柜，其余的走散货。

1楼的不错, 不过有一点需要修改的. 应为:

The total volume of our goods is 32 CBM，so we may book a 20'GP and ship the rest by LCL.

The total volume of our goods is 32 CBM，thus we are going to book a 20'GP,and ship others out by LCL(less container loading).

We are scheduled to book a 20GP due to 32 cbm besides rest will be moved via LCL.
