Answer
393,000 N
Work Step by Step
If the pressure is 14.7 lb/in², then it is at standard pressure, and the pressure is 101.3 kPa. A "pascal" is a unit of pressure and is equal to force of 1 newton per meter.
The area of the can is ....
Area = 2(15.0x40.0) + 2(12.5x40.0) + 2(15.0x12.5)
Area = 2676 cm² or 0.2575 m²
Force = 101300 N/m² x 0.2575 m²
Force = 393,000 N
