Fifteen unit cubes are arranged to form a larger three-dimensional solid. Five cubes form a base laid out in a straight line. Directly on top of the middle three cubes of the base, another layer of three cubes is placed. Above this second layer, a vertical column of two cubes is placed in the center. Beside this column on one side, three cubes are placed horizontally in a single layer. On the other side of the column, two cubes are placed horizontally also in a single layer. Calculate the total surface area of this 3D structure.
