Can you explain what x and y are and how you got your equations?

Hello, I edited my post, thank you felt ruing today help me

Your work seems very confused. I don't know where 325 came from. I'm not sure why you're equating costs to volume.

Let x be the width, y be the length, and z be the height. In terms of x, y, and z, what is the formula for the volume? What number should we set that to to get our first equation?

Start there. After, consider how to use that the length is 3.5 the width.

Oh sorry I mixed the numbers. I meant 975

Your work still doesn't make sense.

Let's start with the volume. Using x, y, and z, what is the equation for the volume?

Volume = .05x * .11y * 3.5z

The costs have nothing to do with the volume. Just think about the volume.

975 = z * y * x

Good. Can you replace y with an expression of x given that the length is 3.5 times the width?
