Mathematics Y7 Surabaya

In this assignment, my role is as the owner of a famous sandwich brand and I have to make a new sandwich packaging for my product, the sandwich packaging must be attractive and use the least amount of paper to reduce the risk of environmental damage, the cost needed to make this packaging should be as cheap as possible and I have to make a net of a product package manually in the paper and then make the design digitally and I have to calculate the volume and the area of the package.

We were tasked to make a sandwich packaging using 3d shapes. In this project, my creativity increased because making the sandwich packaging needs ideas and uniqueness. The first step of this project was to find the problems with everyday sandwich packaging. I made a survey asking people about problems that sandwich packaging has nowadays. I got the result and it says that sandwich packaging is usually not eco-friendly and not unique enough. So I needed to make something that is different than other sandwich packaging.

After I got all the information data I needed I just need to design the packaging. I started by sketching on paper first and determining the length, width, and volume. And after designing the sandwich packaging on paper and calculating the volume I made a cylinder sandwich packaging from cardboard and at last presented it in a report.

There were challenges I faced that were fairly hard because I was confused about how to solve the problem. Like in one of the problems I miss calculated the perimeter of the circle so it made me confused why the paper can’t go around the circle to make a cylinder. And how I overcome this issue by watching and reading tutorials on google and seeing what I did wrong and how can I fix it. It worked for me as I can make the shape perfectly. If I can do this assignment again I would like to design another packaging for other things because this type of assignment it makes me more creative and my problem-solving skill improve.

I have very fond memories of this class like when studying at home I learn so quick and my mother would go “nice job.” my favorite one was the playground project I picked this one because it was one of the easiest ones.

I learned about perimeter and area in this project. I measured the length of the several shapes in my project they are circle, rectangle and prism.

In this survey, I surveyed several people and asked them about their favorite color and why they liked it. After I knew the results, I made a graph of the most favored color. It shows that black is the most favored color in my survey, and I asked them ‘why?’ Most of them answered that it’s neutral and you could match anything with black. In my personal opinion, it is as black is one of my favorite colors. It matches well with your daily life for example, clothing, shoes, cups, and more. Black could also represent mourns and regret, like you see people wearing black to funerals, it meant that they’re grieving. So by doing these assignments, I think I improved my communicative and intelligent competencies.
