The volume of a rectangular prism is (x4 + 4x3 + 3x2 + 8x + 4), and the area of its base is (x3 + 3x2 + 8). If the volume of a rectangular prism is the product of its base area and height, what is the height of the prism?

Respuesta :

Dividing the volume by the base area, you find the height to be ...
[tex] \frac{x^{4}+4x^{3}+3x^{2}+8x+4}{x^{3}+3x^{2}+8}=x+1-\frac{4}{x^{3}+3x^{2}+8}[/tex]

The height of the prism is [tex]x+1-\frac{4}{x^{3}+3x^{2}+8}[/tex]

If the volume of a rectangular prism is the product of its base area and height, than the height of the prism is given by:

[tex]h = (x+1)-\dfrac{4}{(x^3+3x^2+8)}[/tex]

Given :

Volume of rectangular prism [tex]= x^4+4x^3+3x^2+8x+4[/tex]

Base Area of a rectangular prism = [tex]x^3+3x^2+8[/tex]

[tex]\rm Volume = Base \;Area\times Height[/tex]  ---- (1)

Solution :

The volume of prism is the amount of space a prism occupies. It has two same faces and other faces that resemble a parallelogram.

Let the height of the prism be h.

Now, substitute the value of base area and volume of the rectangular prism in the given equation (1).

[tex](x^4+4x^3+3x^2+8x+4) = (x^3+3x^2+8)\times h[/tex]

[tex]\dfrac{x^4+4x^3+3x^2+8x+4}{x^3+3x^2+8}=h[/tex]

[tex]h = \dfrac{((x+1)(x^3+3x^2+8)-4)}{(x^3+3x^2+8)}[/tex]

[tex]h = (x+1)-\dfrac{4}{(x^3+3x^2+8)}[/tex]

If the volume of a rectangular prism is the product of its base area and height, than the height of the prism is given by:

[tex]h = (x+1)-\dfrac{4}{(x^3+3x^2+8)}[/tex]
