Answer :
Answer:
22785 square inches
Explanation:
- As the mass of the tube is 30kg, therefore it is exerting a force of 30g N(30g = 30 × 9.8 = 294)
- So the force is 294 N.
- Pressure is 20 N/m², as given.
- As we know Pressure is equal to the force exerted per unit area (P=F/A).
- Therefore, A=F/P
A = 294 ÷ 20 = 14.7 m²
- As 1 m² = 1550 square inches. Therefore, 14.7 m² = 14.7 × 1550 square inches = 22785 square inches
