We take the earth and put it into a press. It ends up in the shape of a cube. We also slow down its rotation so that one side always faces the sun. Assume that the temperature throughout the cube is uniform. a) Write an equation for the effective radiating temperature of a cube-shaped planet that has a flat side that always faces the sun. (hint: Through how much surface area does the cube absorb radiation relative to the surface area through which it emits radiation?)

b) What is the effective radiating temperature of our cubed Earth? Solve your above equation.
