Answer:
b
Step-by-step explanation:
because volume is like filling and 3d everything else is area and perimeter
Out of all the situations described, the only one where volume would need to be determined is B Sarah wants to know how much water her fish tank can hold.
When it comes to any measurement involving how much water is needed for something, volume is always the best measurement because water is measured in volume. Sarah's situation is therefore the situation that requires volume.

Knowing how much tile to use requires area Knowing how much fence will go around a year requires perimeter Knowing how wide a window is requires measuring the width of the windowIn conclusion, Sarah needs to determine volume to know how much water the tank can hold.
