Answer:

Both objects are packed equally tightly.

Explanation:

For Substance R we have

mass = 10 g

Volume = 22 cubic cm

So we know that density is defined as

[tex]\rho = \frac{m}{V}[/tex]

here we have

[tex]\rho = \frac{10 g}{22 cm^3}[/tex]

[tex]\rho = 0.454 g/cm^3[/tex]

For substance S we have

mass = 25 g

Volume = 55 cubic cm

So we know that density is defined as

[tex]\rho = \frac{m}{V}[/tex]

here we have

[tex]\rho = \frac{25 g}{55 cm^3}[/tex]

[tex]\rho = 0.454 g/cm^3[/tex]

So here both have same density

so correct answer would be

Both objects are packed equally tightly.
