1. The problem statement, all variables and given/known data The problem is attached in the picture. 3. The attempt at a solution I managed to solve it using a different method. I have no idea what the answer is talking about.. My method Found dI of a strip = (1/3)*dm*h2 then i replace h by x, then integrate from -a to a to get the same answer. But as for the answers, I have no clue.
