A furnace is shaped like a long equilateral-triangular duct where the width of each side is 2

Question:

A furnace is shaped like a long equilateral-triangular duct where the width of each side is 2 m. Heat is supplied from the base surface, whose emissivity is ε₁ = 0.8, at a rate of 800 W/m² while the side surfaces, whose emissivities are 0.5, are maintained at 500 K. Neglecting the end effects, determine the temperature of the base surface. Can you treat this geometry as a two-surface enclosure?
