The Volume of a Rectangular Prism: Finding the Height

=====================================================

Introduction

In mathematics, a rectangular prism is a three-dimensional shape with six rectangular faces. The volume of a rectangular prism is calculated by multiplying the area of its base by its height. In this article, we will explore how to find the height of a rectangular prism given its volume and base area.

The Volume of a Rectangular Prism

The volume of a rectangular prism is given by the formula:

V = lwh

where V is the volume, l is the length, w is the width, and h is the height. However, in this problem, we are given the volume as a polynomial expression:

V = x^3 - 3x^2 + 5x - 3

The Area of the Base

The area of the base of the rectangular prism is given by the formula:

A = lw

where A is the area, l is the length, and w is the width. In this problem, we are given the area of the base as a polynomial expression:

A = x^2 - 2

Finding the Height

Since the volume of a rectangular prism is the product of its base area and height, we can set up the equation:

V = Ah

Substituting the given expressions for V and A, we get:

x^3 - 3x^2 + 5x - 3 = (x^2 - 2)h

Solving for h

To solve for h, we can divide both sides of the equation by (x^2 - 2):

h = (x^3 - 3x^2 + 5x - 3) / (x^2 - 2)

Simplifying the Expression

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

h = ((x - 1)(x^2 - 2x + 3)) / ((x - √2)(x + √2))

Canceling Common Factors

We can cancel the common factor (x - 1) from the numerator and denominator:

h = ((x^2 - 2x + 3)) / ((x - √2)(x + √2))

Simplifying the Expression Further

We can simplify the expression further by multiplying the numerator and denominator by √2:

h = ((x^2 - 2x + 3)√2) / ((x^2 - 2))

Final Expression for h

The final expression for h is:

h = ((x^2 - 2x + 3)√2) / ((x^2 - 2))

Conclusion

In this article, we have shown how to find the height of a rectangular prism given its volume and base area. We have used algebraic manipulation to simplify the expression for h and arrive at the final answer.

Example Use Case

Suppose we are given the volume and base area of a rectangular prism as follows:

V = x^3 - 3x^2 + 5x - 3 A = x^2 - 2

Using the expression for h, we can find the height of the prism:

h = ((x^2 - 2x + 3)√2) / ((x^2 - 2))

Code Implementation

Here is a Python code implementation of the expression for h:

import sympy as sp
x = sp.symbols('x')

h = ((x2 - 2*x + 3)*sp.sqrt(2)) / ((x2 - 2))

h = sp.simplify(h)
print(h)

This code will output the simplified expression for h.
