a pile of hot 500C bricks is cooled in a room that has little circulation. calculate the amount of heat released by the brick into the air at the beginning of the cooling time.

big square size : 20 cm x 16 cm x 8 cm

small square size : 10 cm x 8 cm x 4 cm

conduction formula : Fourier law = Q cond = -kA dT/dx

convection formula : Newton law = Q conv = hA (T wall - T air)

value of k and h is unknown. so, just write it with k or h in the calculation
