O Levels Physics (5054)•5054/12/M/J/21

Explanation
Pressure = Weight / Base Area Steps:
- Identify the force: The weight W acts downward on the table.
- Determine the contact area: Without the diagram, the base dimensions (e.g., xy, xz, or yz face) are unknown.
- Calculate pressure: P = W / A, where A is the base area.
- Conclude: Specific area unclear, so pressure expression cannot be determined.
Not enough information.
Why D is correct:
- Cannot confirm; lacks diagram to verify if base area relates to xyz (volume, not area).
Why the others are wrong:
- A: xyz is volume, not area.
- B: yz assumes specific base, unverified.
- C: yz assumes specific base, unverified.
Final answer: Not enough information.
