Your answer is wrong and I have no idea why your talking about feminism. But anyway the affect of surprise was that the natives Americans enemy wouldn't have time to prepare so the losses/casualties for the enemy would be heavy,also using the element of surprise would also most likely scare enemy soldiers, and they would be distracted and confused as well.
Formula : v = 4/3 π r ^3
π = 3.14159265...
V = 4/3 π (12)^3
V = 4/3 π (1728)
V = π (1728)
V = 3.14 (1728)
V = 5425.92
Hope that helps
