HELP...The volume of a rectangular prism is 36x^6y^8. The length of the prism is 4x^3y^5, and the width of the prism is 3xy^2. What is the height of the prism? Write a justification of your result. v=lwh​

Answer:

[tex]H = 3x^2y[/tex]

Step-by-step explanation:

Given

[tex]V = 36x&^6y^8[/tex]

[tex]L = 4x^3y^5[/tex]

[tex]W = 3xy^2[/tex]

Required

Find the height of the prism

Volume (V) is calculated as:

[tex]V =LWH[/tex]

Substitute values for V, L and W

[tex]36x^6y^8 =4x^3y^5 * 3xy^2 * H[/tex]

Make H the subject

[tex]H = \frac{36x^6y^8}{4x^3y^5 * 3xy^2}[/tex]

[tex]H = \frac{36x^6y^8}{4*3x^3*x*y^5y^2}[/tex]

[tex]H = \frac{36x^6y^8}{12x^4*y^7}[/tex]

Divide:

[tex]H = 3x^{6-4}y^{8-7}[/tex]

[tex]H = 3x^2y[/tex]

The height of the prism is: [tex]3x^2y[/tex]
