In the realm of geometry, understanding the relationships between similar figures is crucial. Similar figures, in essence, are shapes that have the same form but different sizes. This relationship is defined by a consistent scaling factor applied to the dimensions of the original figure. In this article, we will delve into the concept of similar rectangular prisms and explore how to determine the scaling factor between them. We will analyze two rectangular prisms with given dimensions and meticulously calculate the factor by which the dimensions of the smaller prism are multiplied to obtain the dimensions of the larger prism. This process involves understanding the properties of similar figures, particularly the concept of proportionality, and applying basic arithmetic operations to arrive at the solution. Our exploration will not only provide a clear understanding of how to calculate scaling factors but also underscore the importance of this concept in various geometric applications.

Before diving into the calculation, it's important to solidify our understanding of similar rectangular prisms. Two rectangular prisms are considered similar if their corresponding sides are proportional. This means that the ratios of the corresponding lengths, widths, and heights of the two prisms are equal. This proportionality is the cornerstone of similarity and allows us to establish a consistent relationship between the dimensions of the two prisms. To illustrate, let's consider two rectangular prisms, Prism A and Prism B. If Prism B is similar to Prism A, then the ratio of the length of Prism B to the length of Prism A should be equal to the ratio of the width of Prism B to the width of Prism A, and also equal to the ratio of the height of Prism B to the height of Prism A. This common ratio is the scaling factor we seek to determine.

The concept of similar rectangular prisms extends beyond simple geometric figures. It is fundamental in various applications, including architecture, engineering, and computer graphics. Architects use the principles of similarity to create scaled models of buildings, ensuring that the proportions are maintained in the final construction. Engineers rely on these principles when designing structures, as scaling models allow for testing and analysis without the need for full-scale prototypes. In computer graphics, similar figures are essential for creating realistic and proportional 3D models. Therefore, understanding the scaling factor between similar rectangular prisms is not just an academic exercise but a practical skill with real-world implications.

We are presented with two rectangular prisms. The smaller prism has the following dimensions:

  • Length: 4.2 cm
  • Width: 5.8 cm
  • Height: 9.6 cm

The larger prism has the following dimensions:

  • Length: 14.7 cm
  • Width: 20.3 cm
  • Height: 33.6 cm

The objective is to determine the scaling factor by which the dimensions of the smaller prism are multiplied to obtain the dimensions of the larger prism. This requires us to compare the corresponding dimensions of the two prisms and calculate the ratio between them. By finding this ratio, we will effectively determine the factor by which the smaller prism has been scaled up to create the larger prism. This scaling factor is a crucial piece of information for understanding the relationship between the two prisms and can be used for various geometric calculations and applications.

To find the scaling factor, we need to compare the corresponding dimensions of the two prisms. We will calculate the ratio of the length of the larger prism to the length of the smaller prism, the ratio of the width of the larger prism to the width of the smaller prism, and the ratio of the height of the larger prism to the height of the smaller prism. If the two prisms are indeed similar, these three ratios should be equal. This is a crucial step in verifying the similarity of the prisms and ensuring that we are working with a consistent scaling factor.

Let's begin by calculating the ratio of the lengths:

  • Ratio of lengths = (Length of larger prism) / (Length of smaller prism) = 14.7 cm / 4.2 cm = 3.5

Next, we calculate the ratio of the widths:

  • Ratio of widths = (Width of larger prism) / (Width of smaller prism) = 20.3 cm / 5.8 cm = 3.5

Finally, we calculate the ratio of the heights:

  • Ratio of heights = (Height of larger prism) / (Height of smaller prism) = 33.6 cm / 9.6 cm = 3.5

We observe that the ratios of the corresponding dimensions are all equal to 3.5. This confirms that the two rectangular prisms are similar, and the scaling factor is indeed 3.5. This means that each dimension of the smaller prism is multiplied by 3.5 to obtain the corresponding dimension of the larger prism. This consistent scaling factor is the key to understanding the relationship between the two prisms and allows us to make predictions about their volumes, surface areas, and other properties.

In conclusion, we have successfully determined the scaling factor between the two similar rectangular prisms. By comparing the corresponding dimensions and calculating the ratios, we found that the dimensions of the smaller prism are multiplied by a factor of 3.5 to obtain the dimensions of the larger prism. This scaling factor is a fundamental concept in geometry and is essential for understanding the relationships between similar figures. The process we followed involved a clear understanding of the properties of similar figures, particularly the concept of proportionality, and careful application of arithmetic operations. The consistent scaling factor confirms the similarity of the prisms and allows us to make predictions about their properties.

The ability to calculate scaling factors between similar figures has broad applications in various fields. Architects use scaling factors to create scaled models of buildings, engineers use them to design structures, and computer graphics professionals use them to create realistic 3D models. Therefore, mastering this concept is not only crucial for academic success in mathematics but also for practical applications in real-world scenarios. By understanding the principles of similarity and scaling factors, we can effectively analyze and manipulate geometric figures, solve complex problems, and create innovative solutions.

In summary, the scaling factor between two similar rectangular prisms is a critical piece of information that reveals the relationship between their dimensions. By carefully calculating this factor, we gain valuable insights into the properties of the prisms and their applications in various fields. This exercise reinforces the importance of proportionality in geometry and highlights the practical relevance of mathematical concepts in the world around us.
