Understanding the Trough Problem: 10ft Pipe with Isoceles Triangle Ends

[JasonRox]

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?

A trough is, erm, something that farm animals eat out of, amongst other things. Just imagine you've got a container that is prism of constant cross section (the triangle) and of length 10ft. That is the trough.

Feet? Oh well. Never mind.

 

[imabug]

take a long section of pipe with a triangular cross section. remove one of the sides and you'll have your trough.

...is that it?

3 feet across the top, from what?

Yes that would be a trough, I would say the distance between the top corner of the trough to the other top corner is 3 feet.

In other words, the trough is 1 feet tall.
