  1. I am curious if you really need to know the volume of the container since you give us the height of the chips and the height of the container.

    1. Hey Evan! I think you’re exactly right. No need to calculate the volume. When I first made this, I thought we might need to know the volume, so that’s why I included the other dimensions.

      This could be a good class discussion. Do we really need all of the given information in Act 2? What information isn’t needed and why?

      Thanks for the comment!

  2. I thought about making a metric version of this, but instead used the opportunity for students to convert inches to cm, which gave practise in multiplying with decimals. (multiply by 2.54).
