How much space can a grenade blow up?

The explosive yield of a grenade can vary depending on its type, but a typical hand grenade can create a lethal radius of about 5 to 15 meters (16 to 50 feet). In terms of the area affected, this can translate to approximately 78 to 706 square meters (840 to 7,600 square feet). However, the actual damage can extend beyond this radius due to shrapnel and blast effects, potentially affecting a larger area.
