Do you know synthetic division?

no I just know we did basically by long division. which is (division, multiplication,subtraction,bring down the next number or term, and repeat.)

Ok. Then divide the volume by x-1 and then divide that answer by x+8 and that will be the length. Or you could multiply (x-1)(x+8) and then divide the volume by that answer.

I came up with the answers x – 6 x – 4 x + 4 x + 6 but I don't know which it is from here.

The length is x+4

The width is x-1 and the height is x+8. That's what the problem says.
