To open a box in English, you can say "open the box" or "unbox the box". This phrasing is derived from the verb "to open", which means "to cause something to be no longer closed or fastened". Here are some example sentences and their translations:

"Can you open the box for me?" (你能把盒子打开吗？)

"I need to unbox this package before I can use the contents inside." (我需要把这个包裹打开才能使用里面的东西。)

"The cat is trying to open the box with her claws." (猫正试图用它的爪子把盒子打开。)

Note: Since you didn't specify what kind of box you're talking about, the above answer is general and can apply to any type of box. If you're talking about a specific type of box (e.g. a jewelry box or a shoe box), you may need to use more specific language to describe it.
