    1. Thanks for asking! I just worked through it and had to try a couple different methods.

      First, I tried just calculating the volume of the donut holes and dividing the volumes of the box and bag by it. That came out to a larger number than the answer.

      Next, I calculated/estimated the amount of donut holes that could fit the length, width, and height of the box and bag, and multiplied. That came out to a more reasonable answer.

      Here’s the PDF of my work.

      Hope that helps!
