Answer:
Both objects are packed equally tightly.
Step-by-step explanation:
For Substance R we have
mass = 10 g
Volume = 22 cubic cm
So we know that density is defined as
![\rho = (m)/(V)](https://img.qammunity.org/2020/formulas/physics/middle-school/n5l1nt5eoo6mhavcn1aunaqrew98hzfkvf.png)
here we have
![\rho = (10 g)/(22 cm^3)](https://img.qammunity.org/2020/formulas/physics/middle-school/o451jdyhnqu163cglvru4sxxtvm82s0b8d.png)
![\rho = 0.454 g/cm^3](https://img.qammunity.org/2020/formulas/physics/middle-school/620gptckq9mab8s528q8prtedoncoaek0c.png)
For substance S we have
mass = 25 g
Volume = 55 cubic cm
So we know that density is defined as
![\rho = (m)/(V)](https://img.qammunity.org/2020/formulas/physics/middle-school/n5l1nt5eoo6mhavcn1aunaqrew98hzfkvf.png)
here we have
![\rho = (25 g)/(55 cm^3)](https://img.qammunity.org/2020/formulas/physics/middle-school/zv6vdcswrcv3bdduf5trjorz2pkq6ygknu.png)
![\rho = 0.454 g/cm^3](https://img.qammunity.org/2020/formulas/physics/middle-school/620gptckq9mab8s528q8prtedoncoaek0c.png)
So here both have same density
so correct answer would be
Both objects are packed equally tightly.
