The length, width, and thickness of a box are x + 5, x + 3, and x - 2. Calculate volume.

Not sure how to proceed.

### Re: Volume

Volume = (x+5)(x+3)(x-2) = (x+5)(x^2-2x+3x-6)=(x+5)(x^2+x-6) = ...

### Re: Volume

(x+5)(x^2+x-6)

Still not sure how to continue.

### Re: Volume

$$(x+5)(x^2+x-6) = x(x^2+x-6) + 5(x^2+x-6) = x^3+x^2-6x + 5x^2+5x-30 = x^3+6x^2-x-30$$
