Homework Equations
V = 1/3*a*b*h
The Attempt at a Solution
I can figure out the coordinates fine for everything except the triangles. I looked at the solution for problem 96 and I can't seem to figure out why the solution is 2/3*66 + 34 (coordinate). I understand that the base would be x/3, or 66/3, which is true for problem 98, so why isn't it problem 96 using 34+ 1/3*66 and instead is using 34 +2/3*66? Any help would be greatly appreciated, as I have spent a long time on this and can't seem to figure it out. Also, would this be same for the y component as well? Thank you very much
