A shipping company needs to calculate the volume of a cubic container with side lengths of 5 feet. How much space does the container occupy?
- A25 cubic feet
- B150 cubic feet
- C250 cubic feet
- D125 cubic feet
Show answer & explanationAnswer & explanation
Correct answer: D. 125 cubic feet
The volume of a cube is calculated by cubing the length of one of its sides (Volume = side³). So, 5 feet × 5 feet × 5 feet = 125 cubic feet.
Why the other options are wrong
- A. This is the area of one face (5 * 5), not the volume.
- B. This is 6 times the area of one face (6 * 25), which is the surface area, not the volume.
- C. This is 10 times the area of one face.
Volume of a Cube
The amount of three-dimensional space a cube occupies.
- Calculated by multiplying length × width × height.
- For a cube, all sides are equal, so V = side³.
- Units are cubic units (e.g., cubic feet, cubic meters).
Memory trick: Volume is how much stuff fits inside the box.
