Question

An open box is made by cutting squares from the corners of a 9 inch by 12 inch rectangular sheet of

cardboard and folding up the sides. Find the maximum volume of the box, along with the size of the

squares to cut from the corners that yield this maximum volume.

Answer 1

V(x) = x(9 - 2x)(12 - 2x)

Expand.

Since Algebra 1 is listed I assume you know how to convert to vertex form.

Do so and determine maximm value.
