Introduction

When it comes to constructing a box with a rectangular base, there are several factors to consider, including the dimensions of the base and the height of the box. In this article, we will explore how to model the volume of a box with a rectangular base using a quadratic equation. We will start by defining the variables and the given information, and then we will derive the quadratic equation that best models the volume of the box.

Variables and Given Information

Let's define the variables and the given information:

$V$ is the volume of the box (in cubic centimeters)
$l$ is the length of the rectangular base (in centimeters)
$w$ is the width of the rectangular base (in centimeters)
$h$ is the height of the box (in centimeters)
$P$ is the perimeter of the rectangular base (in centimeters)

The given information is that the height of the box is 5 cm, and the perimeter of the rectangular base is 28 cm.

Deriving the Quadratic Equation

To derive the quadratic equation that models the volume of the box, we need to use the formula for the volume of a rectangular prism:

V = l \cdot w \cdot h

We are given that the height of the box is 5 cm, so we can substitute this value into the formula:

V = l \cdot w \cdot 5

We are also given that the perimeter of the rectangular base is 28 cm. The formula for the perimeter of a rectangle is:

P = 2(l + w)

We can substitute the given value of the perimeter into this formula:

28 = 2(l + w)

Simplifying this equation, we get:

14 = l + w

Now, we can solve for one variable in terms of the other. Let's solve for $w$ in terms of $l$ :

w = 14 - l

Now, we can substitute this expression for $w$ into the equation for the volume:

V = l \cdot (14 - l) \cdot 5

Expanding this equation, we get:

V = 70l - 5l^2

This is the quadratic equation that models the volume of the box.

Conclusion

In this article, we derived the quadratic equation that models the volume of a box with a rectangular base. We started by defining the variables and the given information, and then we used the formula for the volume of a rectangular prism to derive the quadratic equation. The quadratic equation that models the volume of the box is:

V = 70l - 5l^2

This equation can be used to model the volume of a box with a rectangular base, given the perimeter of the base and the height of the box.
