Question 4320
Volume, V = (x^2 + 5x + 6)(x + 5)   Factor the trinomial.
V = (x + 2)(x + 3)(x + 5)

V = (H )(L)(W)  Since the height of the box is given as:  (x + 2), then the length and width of the base must be: (x + 5) and (x + 3)

Area of the base = (L)(W) = (x + 5)(x + 3) = x^2 + 8x + 15

So, Area of base = x^2 + 8x + 15
