Exploring Volume Changes in a Rectangular Prism: A Comprehensive Guide

In this article, we will explore the effect of changing the height of a rectangular prism while keeping the other dimensions constant. We will delve into the mathematical principles behind the volume change and provide a step-by-step solution to the problem presented.

Understanding Rectangular Prisms and Volume Calculation

A rectangular prism is a three-dimensional shape with six rectangular faces. The volume of a rectangular prism is calculated using the formula:

V LWH

where L is the length, W is the width, and H is the height of the prism.

Initial Conditions

Let#39;s consider the original rectangular prism with a height of 3 inches and a volume of 27 cubic inches. To find the relationship between the dimensions, we can use the volume formula:

V1 LWH

Given that V1 27 and H 3, we can solve for the product of the length and width:

27 LWH 27 LW(3) LW 9

So, the area of the base B LW 9 , in^2.

Changing the Height of the Prism

Now, the height of the prism is changed to 6 inches, while the other dimensions (length and width) remain the same. We can now calculate the new volume using the updated height:

V2 B(H_new) V2 9 , in^2 times 6 , in V2 54 , in^3

This can also be understood by recognizing that doubling the height will double the volume, as the volume is directly proportional to the height.

General Principle of Volume Change

In general, if one dimension of a solid is doubled while the other dimensions remain constant, the volume will be doubled. This principle can be applied to various three-dimensional shapes, including rectangular prisms, cylinders, and other prisms with constant cross-sectional areas.

Conclusion

The change in the height of the rectangular prism from 3 inches to 6 inches, while keeping the length and width constant, results in a new volume of 54 cubic inches. This example illustrates the direct relationship between the dimensions of a rectangular prism and its volume.
