To find the surface area of the entire sculpture, you need to add up the surface area of each part of the sculpture. Overall, you see two triangles connected by two rectangles at the top, and the half of a cylinder at the bottom.
To find the area of one of the two triangles, you use the equation A = (1/2)bh, where b = the base of the triangle and h = the height. So, the area of one triangle is:
