1. I need some bread and some cheese.

2. I need some bread and cheese.

(Are both the same or different in meaning?)

They both mean the same thing, but the second one is better.

yes they both mean the same just the first one, when it adds the other "some" beside the cheese its doesn't need to be there, because it makes the sentence to wordy. Yes to answer your question they both mean the same thing.

Both sentences convey the same meaning that you require both bread and cheese. The only difference is in the structure of the sentences.

In the first sentence, "I need some bread and some cheese," the word "some" is used before both "bread" and "cheese" to indicate that you need an unspecified quantity of both. This implies that you are open to any quantity of bread and cheese.

In the second sentence, "I need some bread and cheese," the word "some" is used only before "bread." However, it is understood that the same "some" applies to both "bread" and "cheese," even though it is not explicitly stated. This sentence is more concise and commonly used in everyday conversation.

So, in terms of meaning, both sentences communicate the same idea of needing both bread and cheese.
