The Ultimate Skis

Hello I am back, this post will revolve around math.

This is fun math, this involves 3D shapes lots of them. We started by learning about the prisms known as triangular and rectangular prisms. These were the main shapes I used to make my part of the project the bindings. These are the things that you clip your boots into when you ware skis. My partner Raymond designed the skis that the bindings go on. Those were more complicated but Raymond managed to make a nice looking pair of skis. After we made the design we had to 3D print them. After that we calculate the measurements and found the volume and surface area. Then we had to find the surface are to volume ratio. We made a key note to present to are class and to show are teacher Mr Gross are work.

These are the two models and the characteristics.

We are being marked on the competency of Communicating and Representing 

this means we had to show are communication to are teacher. Represent means to represent are work which I think we did really well. Over all I would give are work about a 7/10. We did well but I did some things wrong. Anyway I communicated with Raymond a bit to much, that is how we made such compatible models. We made these separately so we could split up the work. We calculated each separately to make it a bit easier. I will admit that I got the easy shapes, Raymonds ones were hard but he did it very well.


Okay lets talk more about the project. Are skis were powder skis the best ones designed, me and Raymond are both huge skiers we ski together all the time. We both wanted skis that glide over the powder so we came up these super wide and flexible skis. The definition of powder skis are wide flexible skis. They are built that way to absorb rough landings and so they bend when you get caught in powder. I want a pair, the only person I know that has a pair is mine and Raymond’s friend julien who is a pro at skiing btw. His are made by a skiing company named blizzard anyway my point is we had an example to build off of. The bindings aren’t different then any other binding you would find on other skis. The skis are twin tip which help you glide on top of the snow. Enough about skis lets get to the numbers.



these are the calculations of the skis they may be a bit blurry. Are V to SA ratio which means volume to surface area, is 3.56:1. The bindings are 2.28:1 so we completed are goal, we wanted more surface area then volume. The skis have more surface area then volume.


we have more competency’s Applying and Innovating, reasoning and analyzing 

we applied a lot of innovation to are world of skis with this project. Not only did we make are own skis but we made skis that would better are performance, I am happy with are results and I think Raymond is as well. We analyzed a lot we analyzed skis, skis and more skis. Trying to find the perfect inspiration for are pair of skis. We also had a big idea, this idea in-tailed the relationship between surface area and volume. His was found in the ratio, every object has some volume and some surface area. The difference is the object will most likely have more of one then the other. I am getting distracted more about the curricular competency’s. We reasoned with loads of numbers we had to divide, subtract, add and multiply. We also had to find lots of formulas like Bxh, LxWxH r2. Those are some of the formulas we used. For apply we applied those formulas to are model to find these math problems and to solve them as well.

This was the project I have been doing for the past four weeks. I have nothing more to say about this project. I am happy with what we made and liked doing this project. Until I write again which will probably be in like twenty four hours. I have to say good bye 👋 👋 👋 👋
