The volume of a rectangular prism is (x3 – 3x2 5x – 3), and the area of its base is (x2 – 2). If the volume of a rectangular pri

To solve the problem we will put the values given to us in the formula of volume of a prism.

<h2>Prism</h2>

A prism is a 3d shape whose two sides are the base sides which are polygon, with the other faces as parallelograms.

The height of the prism is $\dfrac{(x^3-3x^2+5x-3)}{(x^2-2)}$ .

<h2>Explanation</h2>

Given to us

volume of a rectangular prism = (x3 – 3x2 5x – 3),
area of its base = (x2 – 2)
the volume of a rectangular prism is the product of its base area and height,

As given to us,

$\rm{ Volume\ of\ prism = Area\ of\ base \times Height$

$\rm{ Height=\dfrac{Volume\ of\ prism}{Area\ of\ base}$

Substituting the values we get,

$\rm{ Height=\dfrac{(x^3-3x^2+5x-3)}{(x^2-2)}$

Hence, the height of the prism is $\dfrac{(x^3-3x^2+5x-3)}{(x^2-2)}$ .
