Carla made a solid wooden block as shown in the diagram below. She will paint all surfaces of the block.

A prism composed of a rectangular prism and triangular prism, aligned at longest edge of the bottom surface, is shown. The height of the prism is 3 cm, the base is 12 cm long and 10 cm wide. The top face is 6 cm wide. The inclined edge is 5 cm long.

What will be the total painted surface area of the block?
