Introduction

In geometry, a right rectangular prism is a three-dimensional shape with a rectangular base and four rectangular faces that meet at right angles. The volume of a right rectangular prism is a crucial concept in mathematics, and it is essential to understand how to calculate it. In this article, we will explore the relationship between the height and the base of a right rectangular prism and derive an expression for its volume.

The Relationship Between the Height and the Base

Let's consider a right rectangular prism with a square base. The edge length of the square base is $x$ units. According to the problem statement, the height of the prism is 3 units greater than the length of the base. This means that the height can be represented as $x + 3$ units.

Understanding the Volume of a Right Rectangular Prism

The volume of a right rectangular prism is given by the product of its length, width, and height. Since the base is a square with an edge length of $x$ units, the area of the base is $x^2$ square units. The height of the prism is $x + 3$ units. Therefore, the volume of the prism can be represented as the product of the base area and the height.

Deriving the Expression for the Volume

To derive the expression for the volume, we multiply the base area by the height:

Volume = Base Area × Height = $x^2$ × ( $x + 3$ ) = $x^2$ × $x + 3$ = $x^3 + 3x^2$

However, this is not the only possible expression for the volume. We can also factor out the common term $x^2$ from the expression:

Volume = $x^2$ × ( $x + 3$ ) = $x^2$ × ( $x + 3$ ) = $x^2$ × $x + 3$ = $x^3 + 3x^2$

But we can also write it as $x^2(x+3)$ or $x^2x+3x^2$ .

Conclusion

In conclusion, the expression that represents the volume of the prism is $x^3 + 3x^2$ . This expression is derived by multiplying the base area by the height of the prism. The height is 3 units greater than the length of the base, which is $x$ units. Therefore, the height can be represented as $x + 3$ units.

Final Answer

Introduction
