Determine the time required for the center temperature of a 3 cube to reach 808C. The cube has a volume of 125 cm . The thermal conductivity of the material is 0.4 W/(m 8C); density is 950 kg/m3; and specific heat is 3.4 kJ/(kg K). The initial temperature is 208C. The surrounding temperature is 908C. The cube is immersed in a fluid that results in a negligible surface resistance to heat transfer.
