Which situation would require determining volume?


A Nick wants to know how much tile it takes to cover the floor of a room.

B Sarah wants to know how much water her fish tank can hold.

C Min wants to know how much fence is needed to go around the edges of his yard.

D Kiki wants to know how wide her window is.

Answers

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.

The other options are wrong because:

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 window

In conclusion, Sarah needs to determine volume to know how much water the tank can hold.
