Final answer:
The domain of the volume of the cube is b) s³.
Step-by-step explanation:
The domain of the volume of the cube is s³ (Option b). To find the domain, we need to consider what values the side length of the cube, s, can take on.
In this case, the side length can be any positive real number or zero, since it represents a physical measurement. Therefore, the domain of the volume of the cube is s³.
