This is difficult to visualize without a diagram. I'm guessing the base of the triangle has two sides of length 20ft and 14ft with an angle between them of 50 degrees. If so, the area of the triangular base can be found by:

Area = 1/2 x ab x sinC

where a and b are the sides, and C is the angle between them, so the area = 1/2 x 20 x 14 x sin55

Now that we have the area of the base, we can multiply it by the height to find the volume. I'm assuming the height is 1ft, as if the wood is arranged in a 1ft high triangular prism. So the volume = area x height.

If this doesn't seem right based on the diagram, you'll have to either describe the diagram, or try to get a picture.

It seems to me like you decribed it correctly. I have a picture but I do not know how to upload it if possible. Thanks for youe help.
