The block in the drawing has dimensions L0×2L0×3L0, where L0 =0.5 m. The block has a thermal conductivity of 250 J/(s·m·C˚). In drawings A, B, and C, heat is conducted through the block in three different directions; in each case, the temperature of the warmer surface is 35 ˚C and that of the cooler surface is 14 ˚C Determine the heat that flows in 2 s for each case.
