Easy
1. Volume measures:
The amount of three-dimensional space enclosed within an object
The total area of all the outer surfaces of an object
The distance around the outside boundary of a two-dimensional shape
The two-dimensional space enclosed within a shape's boundary
Answer: The amount of three-dimensional space enclosed within an object — Volume is the amount of three-dimensional space enclosed within an object, measured in cubic units.

2. A rectangular water tank is 5 m long, 3 m wide, and 2 m high. What is its volume, in cubic metres, using volume = length x width x height?
Answer: 30 — Volume = length x width x height = 5 x 3 x 2 = 30 m³.

3. Using the same tank (volume 30 m³), and knowing that 1 m³ = 1,000 L, how many litres can this tank hold?
Answer: 30000 — Litres = volume in m³ x 1,000 = 30 x 1,000 = 30,000 L.
