Answer: 110 square inches.
Step-by-step explanation:
The volume of a rectangular box would be:
\(V=length*width*height\)
In this case, we know the volume, the length and the height, and we don't know the width, so we're going to isolate it:
\(width=\frac{V}{length*height}\)
Substituting the data:
\(width=\frac{330}{11*3} =10in\)
This width is also the width of the top of the box, so the area of the top would be:
\(A=length*width\\A=11*10\\A=110in^{2}\)
