Answer 1

X: 72÷12=6
Y: 63÷9=7
so B, Y is more compact

Answer 2

Answer:

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.
