Final answer:
To determine the number of satchel charges required to destroy a sheet metal wall, we need to consider the properties of both the charges and the wall. The specific number of charges needed depends on the strength and thickness of the wall, as well as the power of the charges.
Step-by-step explanation:
To determine the number of satchel charges required to destroy a sheet metal wall, we need to consider the properties of both the satchel charges and the wall. Satchel charges are explosives that release a high amount of pressure upon detonation. Sheet metal walls, although thin, can withstand a certain level of pressure before rupturing or experiencing an explosion.
The specific number of satchel charges needed depends on the strength and thickness of the sheet metal wall, as well as the power of the satchel charges. Unfortunately, the question does not provide this information, so we cannot give an exact answer in this case.
In general, it might take multiple satchel charges to destroy a sheet metal wall. However, the actual number would vary based on the specific circumstances. It is also important to note that using explosives should only be done under controlled and authorized conditions.
