If you mean situations where we use SA and volume to figure out how much of something we need then here are some examples:
We use surface area to see how much wrapping paper is used to cover a gift.
We use surface area to find out how much paint you would need to paint a wall.
For volume:
We use volume to see how much water a pool needs.
We use volume to see how much of something you need for a recipe (when measuring ingredients in a cup).
Hope this helps!
