The denser an object, the more compact it is. the table below shows the mass and volume of two different objects. comparison of liquidsliquid    mass (g)            volume                                        cm3)x              72                      12y              63                          9which of the two objects is more compact? aobject x is more compact. bobject y is more compact. cboth objects are equally compact. d this cannot be determined.

B) Object Y is more compact.

Step-by-step explanation:

We have 2 objects, X and Y, with their respective masses and volumes.

Liquid    Mass (g)           Volume  (cm³)

   X             72                      12

   Y             63                       9

The density (ρ) is equal to the mass (m) divided by the volume (V).

ρ = m/V

For these objects,

ρX = 72 g / 12 cm³ = 6.0 g/cm³

ρY = 63 g / 9 cm³ = 7.0 g/cm³

The denser an object, the more compact it is. Then, Object Y is more compact.

the fist one is not equalvalent but i think th second one isand the third isnt definetly or the last one is i think. hope this !

step-by-step explanation:

they would have to work 32 hours.
