S2-S1 = 3 S2 = 3+S1 Jadi, S2^2 - S1^2 = 234 (3+S1)^2 - S1^2 = 234 9 + 3S1 + 3S1 + S1^2 - S1^2 = 234 9 + 6S1 = 234 6S1 = 234-9 6S1 = 225 S1 = 225/6 S1 = 37,5 Jadi : S2 = 3+S1 S2 = 3 + 37,5 S2 = 40,5 Lalu : V = S^3 Jadi : Selisih V = V2-V1 = (S2^3) - (S1^3) = (40,5)^3 - (37,5)^3 = 66430,125 - 52734,375 = 13695,75
