How much TNT would it take to destroy a building?

The amount of TNT required to destroy a building varies significantly based on factors such as the building's size, construction materials, and structural integrity. For example, a small residential building may require around 10 to 30 pounds of TNT, while larger commercial structures could need several hundred pounds or more. Additionally, the method of demolition and the desired level of destruction influence the amount of explosives used. Proper engineering assessments are crucial to determine the specific requirements for any demolition project.
