# How do we find the maximum volume of a box?

By Marietta Geraldino

Do you want to learn the ‘maths’ behind creating an open box from a rectangle with squares cut out of the corners? If so, this video is for you. You will learn how to write the volume of the box as a function of x, find the domain of the function​ and describe the restrictions, find the dimensions of the square cut out, and determine the maximum volume of the box using graphical method and derivative.
