#3 and #4 please. How do you know a sticky note has volume and can you determine the volume of an entire stack by knowing the volume of a single sticky note

Answer:
Step-by-step explanation:
3. A single sticky note is a three-dimensional object. Meaning it has a length, width and height. Therefore, it is taking up space, and anything that takes up space has a volume. If the sticky not did not have a volume then it would not be a three-dimensional object.
4. Yes, if we knew the volume of a single sticky note, then we would simply have to multiply the volume of that individual note by the total number of sticky notes in the pile. This would give us the volume of the entire pile.
