A ceramic brick with dimensions $120$ mm x $120$ mm x $240$ mm is cooled from an initial uniformtemperature of $130\backslash$deg C in air which is at $30\backslash$deg C$.$ If the density of the cube is $2050$ kg m$-3,$ thespecific heat capacity is $960$ J kg$-1$ K$-1,$ the thermal conductivity is $1\mathrm{.}0$ W m$-1$ K$-1,$ and the heattransfer coefficient of the air around the brick is $60$ W m$-2$ K$-1,$ calculate the temperature atthe centre, and the corner of the cube after $1(1)/(2)$ hours as well as the quantity of heat that hasbeen transferred from the brick to the air at this time.
