The edge length of the cube is 5cm. First, a small cube with an edge length of 1cm is dug out from each of the four vertices, and then a small cube with an edge length of 1.5cm is dug out from the remaining four vertices. If a small cube with a side length of 1 cm is glued to the center of the surface, what is the surface area of the object?
正方体棱长为5cm，先从其中四个顶点处各挖去一个棱长为1cm的小正方体，然后在剩余的四个顶点处各挖去一个棱长为1.5cm的小正方体，最后在原来各面的中央粘上一个棱长为1cm的小正方体，则物体的表面积=多少．
