    Need help with a volume type of question

    The height of a square-beased box is 4 cm more than the side length of its square base. If the volume of the box is 225 cm cube, what are the dimensions.

    Please also explain, I have no idea

    Thanks

    Here's a start. let the side length of the base be x. then the height is (x + 4). now, volume is length*width*height, thus we have


    225 = x*x*(x + 4)

    now, solve for x and you can find the dimensions

    It has a square base. What does that imply about its width in relation to its length?
