Introduction

In mathematics, a rectangular prism is a three-dimensional shape with length, width, and height. The volume of a rectangular prism is given by the product of its length, width, and height. In this article, we will explore how to find the expression representing the width of the box given the volume and the length and height of the box.

The Volume of the Rectangular Prism

The volume of a rectangular prism is represented by the function $x^3+9x^2+6x-16$ . This function is a polynomial of degree 3, which means it has three terms with different powers of $x$ . The volume of the box is given by the product of its length, width, and height.

The Length and Height of the Box

The length of the box is given by the expression $x+2$ , while the height is given by the expression $x+8$ . These expressions are linear functions of $x$ , which means they have a constant coefficient and a variable term.

Finding the Width of the Box

To find the expression representing the width of the box, we need to divide the volume of the box by the product of its length and height. This can be represented by the following equation:

\text{Volume} = \text{Length} \times \text{Width} \times \text{Height}

Substituting the given expressions for the volume, length, and height, we get:

x^3+9x^2+6x-16 = (x+2) \times \text{Width} \times (x+8)

To find the width, we need to divide both sides of the equation by the product of the length and height:

\text{Width} = \frac{x^3+9x^2+6x-16}{(x+2) \times (x+8)}

Simplifying the Expression

To simplify the expression, we can factor the numerator and denominator:

\text{Width} = \frac{(x+2) \times (x+8) \times (x+1)}{(x+2) \times (x+8)}

Canceling out the common factors, we get:

\text{Width} = x+1

Conclusion

In this article, we have found the expression representing the width of the box given the volume and the length and height of the box. The width of the box is represented by the expression $x+1$ . This expression is a linear function of $x$ , which means it has a constant coefficient and a variable term.

The Final Answer

$The final answer is: $\boxed{x+1}$<br/> **The Volume of a Rectangular Prism: Q&A**$

Introduction

In our previous article, we explored how to find the expression representing the width of the box given the volume and the length and height of the box. In this article, we will answer some common questions related to the volume of a rectangular prism.

Q: What is the volume of a rectangular prism?

A: The volume of a rectangular prism is the product of its length, width, and height. It can be represented by the function $x^3+9x^2+6x-16$ .

Q: How do I find the width of the box given the volume and the length and height of the box?

A: To find the width of the box, you need to divide the volume of the box by the product of its length and height. This can be represented by the following equation:

\text{Volume} = \text{Length} \times \text{Width} \times \text{Height}

Substituting the given expressions for the volume, length, and height, you get:

x^3+9x^2+6x-16 = (x+2) \times \text{Width} \times (x+8)

To find the width, you need to divide both sides of the equation by the product of the length and height:

\text{Width} = \frac{x^3+9x^2+6x-16}{(x+2) \times (x+8)}

Q: Can I simplify the expression for the width of the box?

A: Yes, you can simplify the expression for the width of the box by factoring the numerator and denominator:

\text{Width} = \frac{(x+2) \times (x+8) \times (x+1)}{(x+2) \times (x+8)}

Canceling out the common factors, you get:

\text{Width} = x+1

Q: What is the final answer for the width of the box?

A: The final answer for the width of the box is $\boxed{x+1}$ .

Q: Can I use this method to find the width of a rectangular prism with different dimensions?

A: Yes, you can use this method to find the width of a rectangular prism with different dimensions. Simply substitute the given expressions for the volume, length, and height into the equation:

\text{Volume} = \text{Length} \times \text{Width} \times \text{Height}

And then divide both sides of the equation by the product of the length and height to find the width.

Q: What are some real-world applications of finding the volume of a rectangular prism?

A: There are many real-world applications of finding the volume of a rectangular prism, such as:

Calculating the volume of a box or container
Finding the volume of a rectangular prism with different dimensions
Calculating the volume of a prism with a non-rectangular base
Finding the volume of a prism with a non-rectangular cross-section
