B is inversely proportional to the cube of A. If B=3, A=2. If B = 8/9. Find the value of A. A. 2 B. 3 C. 4 D. 6 Answer Workspace Report Discuss Answer with explanation Answer: Option B Explanation As per the question, B is inversely proportional to A3 i.e., B α 1/A3 Or, B =k/ A3 Given that, B=3, A=2 So, 3 = k/ 8, or k=24 Given that, B = 8/9 So, 8/9 = 24/A3 A3 = (9*24)/8 = 27 So, A = 3√ 27 = 3 Workspace
