Question

Find an algebraic expression that represents the volume of the figure. 5x-3, x+6, x?

volume

Answer 1

`5x^3+27x^2-18x`

Explanation:

I assume the numbers you've given are the dimensions of the figure. If so, then the volume is these all multiplied - length`times` height `times` width

`(5x-3)*(x+6)*x`
`(5x-3)(x^2+6x)`
`5x^3+30x^2-3x^2-18x`
`=5x^3+27x^2-18x`
