a. Express the volume V of the box as a function of x.
b. State the domain of V.
Each side of the square would look like x--------x, if the length started out as 30 inches, then each side would be 30-2x.
V=L*W*H
The height is x.
Length and width are the same because it has a square base.
a.
b.Each dimension has to be greater than 0.
x>0 and 30-2x>0
30-2x>0
-30+30-2x>0-30
-2x>-30
-2x/-2<-30/-2
x<15in
Therefore is the domain.
Interval notation: (0,15in)
