Chemistry questions on finding thickness of aluminum foil and indirect observations?

I have no clue how to put these lab questions into sentences i've done all the work but i'm stuck on these questions1) How can the thickness of a piece of aluminum foil be determined, without actually measuring it?2) What does indirect observation have to do with the topic of atomic structure ?

Answer:

If you had Al foil and could cut it into a regular shape like a circle or a rectangle, you could measure the surface area with a rulerThen you could measure its mass on a balance and use the known density to calculate the volumeIf you had a rectangle, you would set that volume equal to the area times the thicknessYou now have the thickness without having directly measured it In atomic structure, many values (like atomic radius) have to be measured indirectly.
