A dollhouse has a volume given by the trinomial y^3 - 5y^2 - 6y. What are possible dimensions of the box?
I've been having trouble with this question all day. Can somebody help me?

factor the polynomial and you have
y(y-6)(y+1)
so, as long as y>6 some possible dimensions are
7x1x8
8x2x9

Can you not? My factorization gives the three dimensions. Look at the last choice.
