Some airlines have restrictions on the size of items of luggage that passengers are allowed to take with them. suppose that one has a rule that the sum of the length, width and height of any piece of luggage must be less than or equal to 210 cm. a passenger wants to take a box of the maximum allowable volume. if the length and width are to be equal, what should the dimensions be? length = width = height = in this case, what is the volume? volume = (for each, include units)if the length is be twice the width, what should the dimensions be? length = width = = in this case, what is the volume? volume = (for each, include units)
