A small rectangular tank measures 7 m by 4 m by 3 m. What volume of water can it hold?
Note
The tank capacity in cubic metres is its volume: 7 × 4 × 3 = 84 m³. Volume is measured in cubic units because it counts three dimensions: length, width, and height. A rectangular tank is a cuboid, so its capacity is found by multiplying length, width, and height. The answer is in cubic units because it tells how much space the tank can hold.
