The block in the drawing has dimensions LoxLox3Lo,where Lo =0.5 m. The block has a thermal conductivity of 150 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 23 .C and that of the cooler surface is 12 'C Determine the heat that flows in 9 s for each case.
