I have recieved two different answers I would like someone's third opinion on which is correct and to show the work for the correct one. Attached is the problem as well as the two answers.

It's true — sand dunes in Colorado rival sand dunes of the Great Sahara Desert! The highest dunes at Great Sand Dunes National Monument can exceed the highest dunes in the Great Sahara, extending over 700 feet in height. However, like all sand dunes, they tend to move around in the wind. This can cause a bit of trouble for temporary structures located near the "escaping" dunes. Roads, parking lots, campgrounds, small buildings, trees, and other vegetation are destroyed when a sand dune moves in and takes over. Such dunes are called "escape dunes" in the sense that they move out of the main body of sand dunes and, by the force of nature (prevailing winds), take over whatever space they choose to occupy. In most cases, dune movement does not occur quickly. An escape dune can take years to relocate itself. Just how fast does an escape dune move? Let x be a random variable representing movement (in feet per year) of such sand dunes (measured from the crest of the dune). Let us assume that…

20. Eunice is planning to buy a cake whose box has dimensions 18 in by 18 in by 18 in. Since the cake melts easily, she also plans to buy ahead an insulated box whose length is equal to its width which is 5 inches longer than its height and has a volume of 6 000 cu in. Is the size of the insulated box enough for her box of cake? * A. Yes, because the volume of the box of the cake is smaller than the volume of the insulated box. B. Yes, because dimensions of the insulated box are longer than the cake box. C. No, because the width of the cake box is smaller than the height of the insulated box. D. No, because the height of the cake box is longer than the height of the insulated box.

Hey, I need the answers to this. NOW PLEASE, and with DETAILS. Thanks
