A cardboard sheet has a width of 16 inches and a length of 18 inches. An open box is made from the sheet by cutting out squares W inches on a side from the four corners. Express the volume of the box as a function of W .

V(w)= (18-2x)*(16-2x)*x

Don't know how you submit your answers, but are you using "x" or "w" in it??

I;m looking at that and know it used to be a piece of cake, but it's been many moons since I've integrated anything.

Let's see....

The last time I used calculus was in college Calculus class....

That was over a decade ago....

Yup, I forgot it all, already, lol.

i dropped calc... only class in my entire school career I Just couldn't understand

i think the answer should be:

V(w)=4w(cubed) - 66w(squared)+ 288w

basically the same as you had just multiplied out... give it a shot at least
