Context
Mathematics is an incredibly powerful tool that allows us to quantify the world around us. When we look at a building, a box, or a package, we are seeing three-dimensional shapes, also known as solids. Specifically, we are talking here about a type of solid called a rectangular prism. This is a concept you have probably encountered before, but why is it so important?
The answer to this question lies in the word 'quantify.' Mathematics allows us to measure things. When we talk about a rectangular prism, we can measure its length, width, and height. But it doesn't stop there; if we know these three measurements, then we can calculate the volume of the prism. And volume, as you probably already know, is the measure of how big an object is in three dimensions.
Volume is a key concept that is everywhere in the real world. It is the measure of how much space a certain amount of material occupies. Imagine you are packing things for a move. You need to know how much space your things will take up in the moving van. And guess what, volume is exactly what you need!
The concept of volume is also fundamental in engineering and physical sciences. From building construction to measuring the amount of liquid in a tank, volume is indispensable. Furthermore, volume also plays an important role in art, especially in sculpture and architecture.

Practical Activity: Creation of Models and Volume Calculation
Project Objective
Each group will create a rectangular prism and calculate its volume. In addition, students will also research real-world examples where the volume of the rectangular prism is relevant and creatively present their findings to the class.
Detailed Project Description
The project will be carried out in groups of 3 to 5 students over a month. Each group will be responsible for creating a model of a rectangular prism using recyclable materials. Additionally, each group must calculate the volume of the rectangular prism they created.
At the same time, students should research real-world examples where the volume of the rectangular prism is used and relevant. It can be in engineering, art, everyday life, etc. Students should creatively present these examples to the rest of the class.
Required Materials
- Recyclable materials for building the model (cardboard boxes, plastic bottles, old newspapers, etc.)
- Tape measure to measure the dimensions of the model.
- Computer with Internet access for research.
- Paper and pen to write down calculations and research findings.
Activity Steps
- Form groups of 3 to 5 students.
- Each group should create a model of a rectangular prism using recyclable materials.
- Using the tape measure, students must measure the dimensions of the model (length, width, and height) and calculate the volume of the rectangular prism.
- While building their model, students should research real-world examples where the volume of the rectangular prism is relevant.
- Each group will present their model, the calculated volume, and the real-world examples to the rest of the class.
- Each group will prepare a detailed written report on the project.
Project Deliverables
At the end of the project, groups must deliver the model of the rectangular prism, an oral presentation on the model and real-world examples, and a detailed written report.
The written report should include an introduction where students explain the concept of rectangular prism and volume, and the importance of volume in the real world. Then, in the development section, students should explain how they built the model, how they calculated the volume, and how they found the real-world examples. Finally, in the conclusion, students should reflect on what they learned during the project. The report should also include a bibliography related to the research conducted for the project.
Students should dedicate between five to ten hours to complete the project, including building the model, research, and report writing.
