6 miles or 31680 feet.
Mount St. helens is 12,678 feet tall and 1.6 miles wide and the base is 6 miles wide.
Before the huge eruption on May 18, 1980, Mount St. Helens was 9,677 feet. After the eruption, Mount St. Helens was 8,363 feet. A total for 1,314 feet was removed by the May 18th eruption.
As I think, the base and breadth or width are same . Because as the width expresses the land the way base does the same thing.
the volume is (base)(height)(width) ... base x height x width
Mount for a scope.
The base is halved so, so too does the width need to be. 11/2 is 5.5 inches.
base*width*height
length 'times' width
213
It is width*length
It is width*length
