Question

I need to Find the volume of a rectangular prism if the length is 4x, the width is 2x, and the height is x^3 + 6.

Answer 1

Given that

length = 4x

width = 2x

height = x^3 + 3x + 6

`\begin{gathered} V=lwh \\ \\ \Rightarrow V=(4x)(2x)(x^3+3x+6) \\ \\ \Rightarrow V=8x^2(x^3+3x+6) \\ \\ \Rightarrow V=8x^5+24x^3+48x^2 \end{gathered}`

The correct option is C
