Question

The volume of a rectangular box is 330 cubic inches. The length on one side of the top is 11 inches, and the height of the box is 3 inches. What is the area of the top of the box.

Answer 1

Answer: 110 square inches.

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=(V)/(length*height)`

Substituting the data:

`width=(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)`
