Our first 2 were almost perfect but our third one was far too short and to wide, its top
was also slanted
19.
The height was the hardest to control due to the standard deviation being far more than
the others. It was harder due to having to figure out the orientation of the squares and cutting
it wrong
21.
1-Townes and Aaron measures all the parts
2-Alex and Townes cut all the parts needed
3-Alex and Aaron glue the box together
4-Townes measures final product and trims off excess
(Repeat for every box)
Conclusion Questions:
1. We exceed our expectations for our first box and completed it 10 minutes faster than
predicted
2. It was more efficient even if the final product wasn’t the best
3. It is the last step
4. No, our standard deviation was sometimes over 1 inch which is insane
5. Yes, we did plan for it to be very precise and our groups first two boxes were very
precise all except for the third box
