An open box is going to be made from a square piece of material, 30 inches on each side, by cutting equal squares from the corners and tuning up the sides. Write an equation for the volume of the box.

Answer 1

Let x = the box height

If you fold up two sides, the width of the 30 in, the new width will be (30-2x)

This will also be the length, since it is a square

Volume = l x w x h Plugging in the box dimensions:

V=(30-2x)(30-2x)(x) You can multiply out if needed.
