How do you find the surface area of a rhombicosidodecahedron (62-sided polygon)?

I built one of construction paper, and each square, triangle, and pentagon has sides of 2". There are 12 pentagons, 30 squares, and 20 triangles (I think). What is the surface area? Or even if you don't want to do the math, how do you FIND the surface area of it?
