Contextualization
Welcome to the fascinating world of geometry! In this project, we will be exploring a specific area of geometry, known as spatial geometry, and more specifically the concept of surface area. This concept relates to the total area that the surface of a three-dimensional object occupies. We will focus on a particular shape, the prism, and learn how to calculate its surface area.
Prisms are three-dimensional objects that have two parallel and congruent bases. The other faces of the prism are parallelograms. These parallelograms are called the lateral faces. The height of the prism is the perpendicular distance between the bases. By understanding the properties of prisms, we can determine their surface area.
The surface area of a prism is the sum of the areas of its bases and its lateral faces. This means that to find the surface area of a prism, we need to calculate the area of each of these parts and then add them together.
Introduction
The concept of surface area is not just a theoretical one. It has numerous practical applications in our daily lives. For example, when you wrap a gift, you have to cover all its sides. The amount of wrapping paper you'll need for each gift will depend on the size of the gift, which is directly related to the surface area of the gift.
Similarly, when you're painting a room, you need to know the surface area of the walls and the ceiling to determine how much paint you'll need. Architects and builders use the concept of surface area when calculating the amount of material needed for construction projects, such as bricks, tiles, or paint.
In the real world, the concept of surface area is not confined to prisms. It applies to all sorts of three-dimensional objects, from the simplest ones like cubes and cylinders to complex ones like buildings, cars, or even our planet Earth!

Practical Activity
Activity Title: "Building and Calculating: Understanding the Surface Area of a Prism"
Objective of the project:
To apply the concept of surface area of a prism in a real-world scenario, and to enhance teamwork, problem-solving, and creative thinking skills.
Detailed description of the project:
The project involves the creation of a life-sized model of a prism using cardboard or any other suitable material. The prism should be a rectangular one, with each face being a rectangle. The dimensions of the model should be such that the calculations for its surface area involve the use of whole numbers or simple fractions.
Each group will design their own prism, determine its dimensions, calculate its surface area, and then construct the model based on these calculations. The group will also need to present their findings and the process they followed to the class.
Necessary materials:
- Cardboard or any other suitable material for constructing the prism.
- Ruler or measuring tape.
- Pencil and eraser.
- Scissors or a cutter.
- Glue or tape.
- Markers or colored pencils.
- Calculator.
Detailed step-by-step for carrying out the activity:
-
Planning Phase: As a group, decide on the dimensions of your prism. The dimensions should be such that the calculations for its surface area can be easily carried out. For example, the length, width, and height of the prism could be 10 cm, 5 cm, and 3 cm respectively.
-
Calculating Phase: Using the dimensions of your prism, calculate its surface area. Remember, the surface area of a prism is the sum of the areas of its bases and its lateral faces.
-
Design Phase: Draw a scaled model of your prism on a sheet of paper. Ensure the dimensions of the model are proportional to the dimensions of the real prism.
-
Construction Phase: Use the drawn model as a guide, and construct the prism using the cardboard or the chosen material. Make sure all the dimensions of the constructed prism match those of the drawn model.
-
Decoration Phase: Decorate your prism to make it visually appealing. You can use markers, colored pencils, or any other materials you like.
-
Presentation Phase: Prepare a presentation for the class. The presentation should include details about your prism, the calculations you made for its surface area, and the process you followed to construct it. It should also highlight any challenges you faced and how you overcame them.
Project Deliverables and Written Document:
At the end of the project, each group should submit a written document that contains the following sections:
-
Introduction: Discuss the concept of surface area, its real-world applications, and the objective of the project.
-
Development: Detail the theory behind the concept of surface area, explain in detail the activity that was carried out, including the methodology used to calculate the surface area and construct the prism, and present and discuss the obtained results.
-
Conclusion: Summarize the main points of the project, state the learnings obtained, and draw conclusions about the project.
-
Bibliography: Indicate the sources you relied on for the project. These can include books, web pages, videos, or any other resource.
The written document should complement the practical part of the project and provide a comprehensive overview of the work done by the group. The document should be neatly formatted and free of grammatical and spelling errors.
Remember, the goal of this project is not just to understand the concept of surface area, but also to apply it in a practical and creative way. Have fun, be creative, and enjoy the process of learning!
