PLEASE HELP ME AND ANSWER ALL THE PARTS TO THE PROBLEM

Answer 1

Hi!

Since the volume of a box is given by l*w*h (so I assume it's a parallelepiped), you have to multiply all the inches of the box.

For example, the small box has x = width, x+2 as lenght and 2x as height.

So you multiply all of them together.

Small box volume: x(2x)(x+2) [expression]

Large volume box: (x+5)(x+7)(3x)

The difference is that the large box contains more things, since it has a bigger volume.

If you solve both expression, you'll find that small box volume is 2x^3 + 4x^2 and that large box volume is 3x^3 + 36x^2 + 105x
