# A pyramid has a base in the shape of a rhombus and a peak directly above the base's center. The pyramid's height is #5 #, its base has sides of length #1 #, and its base has a corner with an angle of # pi/4 #. What is the pyramid's surface area?

T S A is 20.8067

AB = BC = CD = DA = a = 1

Height OE = h = 5

OF = a/2 = 1/2 = 0.5
