Hi Steve,
You helped me with a question earlier today about finding surface area of a triangular prism with the base being an equilateral triangle . I got the answer 386.6 Is this correct.? I tried to follow your equation and am having a bit of trouble. Thanks for all your help.

That's what I get.
if you have a hard time figuring the area of an equilateral triangle, it's time for some further review. It's a 306090 right triangle on each side of the altitude because each angle of the main triangle is 60 degrees.posted by Steve
