Answer: (B) Object Y
Explanation: the reason it is Y is because as quoted "Since density is mass per volume, the most straight forward way of measuring the density of something is to measure its mass, then measure its volume and divide the mass by the volume." so first you have to divide 72/12=6 and 63/9=7 so then once you get this answers you have to look closer at them object x=6 object y=7 so even though object x has a bigger mass object y is more dense. i hoped this helped if you can i would love the brainiest but if not that is ok have a great day bye.:)
