What's the main difference between "bag" and "sack"? Can't I say "sack" in this context?

In this context, you could use "sack" instead of "bag". A "sack" is a type of "bag". You use "sacks" to store food in large quantities, like the corn in this case. It is a large bag made out of strong material, like canvas. Ex: There was a sack of flour in the cupboard that I couldn't reach. Ex: Can you get me a small bag of crisps for the road? Ex: Sarah thought she could turn the old sack she found into a doormat.
