This is the beginning of a question and I have NO clue what the hell they are talking about. A trough is 10ft long and its ends have the shape of isoceles triangles that are 3ft across at the top and have a height of 1ft. This is just the beginning of the question. I looked up what trough is and I found it to be some sort of pipe. I can't solve the problem without this. I'm thinking of a pipe that is 10 feet long and 1 feet high. That is the volume of a cylinder. Plus, 2 cones on the tips of some kind. I really don't know. Any help?
