Question

i. a box that has nothing inside using suitable adjective​

Answer 1

Answer:

Inside can be used in the following ways:

as a preposition (followed by a noun): What’s inside the envelope? Inside of is sometimes used instead of inside, especially in American English: I had a strange feeling inside of me.

as an adverb (without a following noun): I opened the box and looked inside.

as an adjective (always before a noun): the inside pages of a newspaper
