To determine which object is more compact, we need to calculate their densities. Density is calculated by dividing the mass of an object by its volume.
For object X:
Density of X = Mass of X / Volume of X = 72 g / 12 cm3 = 6 g/cm3
For object Y:
Density of Y = Mass of Y / Volume of Y = 63 g / 9 cm3 = 7 g/cm3
Since the density of object Y (7 g/cm3) is greater than the density of object X (6 g/cm3), this indicates that object Y is more compact.
Therefore, the answer is:
b Object Y is more compact.
The denser an object, the more compact it is. The table below shows the mass and volume of two different objects.

Which of the two objects is more compact?
a Object X is more compact.
b Object Y is more compact.
c Both objects are equally compact.
d This cannot be determined.
