Puzzle Cube Challenge Part 2

The Goal- Create two designs for your 3x3x3 cube. You can't use the same piece shape more than once.

Puzzle Cube Challenge Part 1

The Goal- Find all possible combinations for 3 cubes, 4 cubes, 5 cubes, and 6 cubes while following all the constraints and criteria.

These pieces would have to be able to form a 3x3x3 cube in the end, so for example you couldn't make a piece just for cubes in length.

1st Achievement
         Make a boat that will be able to float 103lbs of Josh.
  1. Pointed bow
  2. Wings
  3. Keel
  4. V-Bottom
  5. Support Bars
  6. Large amount of surface area
  7. Make it as small as possible
  8. Flat Bottom
  9. Make a rudder
  10. Make a seat
  11. High Walls

  19. Make a surfboard with 3" walls
  20. Make a simple box
2nd Achievement
         Implied Criteria: It must stay in one piece throughout the course

         Implied Constraints: Must fit through the doorway, we have a limited amount of time to construct it, and it has to be large enough to fit one of us.

3rd Achievement- See previous posts for Sketch Ideas

4th Achievement- See previous post for Model

5th Achievement
          Approach- A v-bottom design
  +It will obtain one of the achievements
  Change: Make the bow pointed to help it go smoother through the water
  ? Will it even stay up or will it roll over right away?
  ! Some kind of wings for balance

6th Achievement
        Surface Area: 60 yards x 1.88 inches x 3 rolls
        180 ft x 0.15667 ft x 3 rolls
        28 ft squared x 3 rolls
        84 ft squared
7th Achievement
        I believe we should get this achievement because we did complete all of the criteria. Unfortunately we did not get a picture before we put our boat in the water, and it's understandable if that makes our team invalid for it.

8th Achievement
       V-Bottom: We were very proud of our v-bottom, and that we were the only team in our period to do so!

9th Achievement
       Balance Master: Under about a foot of water Josh was able to stand in the bottom of our boat for five seconds.

10th Achievement
        Feedback
  1. Change- More layers of duct tape on the stern
  2. + It didn't roll over like I expected it to
  3. ! I think the wings helped a little
  4. ? Would it had made a difference if we built a keel
  5. Change- Make the wings longer
  6. ? If the rope didn't break would it have helped us at all
  7. ! It wasn't a complete failure
  8. ? Was it worth taking the risk of it not staying upright
  9. Change- Make a more sturdy base
  10. + The extra strip of cardboard on the v-bottom helped it keep it's shape
11th Achievement
       How Low Did You Go?
           Surprisingly we remained above water for a few minutes. The water that came into the boat came in through the back at the bottom because there was a small hole. Even after it was completely under water it was only a little more than a foot deep. The Surface Area displaced enough water to keep Josh afloat.

12th Achievement
      Stick Through It: As a team we faced some challenges on equal work for everybody. I also was absent for a full period and a half which caused us to get behind in work. Even with these problems we stuck together as a team and had a really great time in the pool with our finished boat.

Model of Sketch #1

Model #1

Sketch #3

Sketch #3- Made for Speed and Balance (Arial View)
1.) Pointed bow-to move freely through the water
2.) Support bars to prevent sides from collapsing
3.) Non-flat bottom-moves easier through the water and to complete one of the challenges
4.) Wings-to take up surface area and to provide balance
5.) Keel-to hopefully prevent it from tipping over so easily
