A steel cube is to be heated from 120°C to an average temperature of 180°C in 45 minutes. One side of the cube is 50 cm in length. Taking the average density and specific heat of steel in this temperature range to be ρ = 7,950 kg/m 3 and c p = 0.49 kJ/kg·°C, respectively, determine a) the total amount of heat transfer to the steel cube, b) the average rate of heat transfer to the cube, C) the average heat flux.
