Hi All,

I've run into a problem with calculating the volume of a frustum and was hoping for some assistance.

I have the following information:

- The slopes are exactly 45°.

- The base must fit on an area exactly 50 meters on a side.

- The height is 10 meters.

R1 and H are easy enough, but I'm not sure how to determine R2. I know the slope angle should help, but I'm not sure how.

j.k.
