Question 110706
V=LWH  where L is length, W is width and H is height

Area of the bottom=LW

So
LWH=(x^2+5x+6)(x+5) but note that x^2+5x+6 can be factored:
The factors are (x+3)(x+2)

Since we are told that x+2 is the height, then the length and width must be:

(x+3)(x+5) so:

Area of bottom =LW=(x+3)(x+5)

Hope this helps---ptaylor
