What does volume measure in a 3D object?

• The weight

• The surface area

• The perimeter

• The space it occupies

What is the difference between surface area and volume?

• Surface area is measured in cubic units, volume in square units

• They are the same

• Volume measures the outer shell, surface area measures space occupied

• Surface area measures the outer shell, volume measures space occupied

Why is it important to understand different terminologies in geometry?

• To pass tests

• To make geometry more complicated

• Because different teachers may use different terms

• Terminology is not important
