i need the answer quickly 4-12 Astack of common building brick 1 m high, 3 m long, and 0.5 m thick leaves an oven,where it has been heated to a uniform temperature of 300°C. The stack is allowedto cool in a room at 35°C with an air-convection coefficient of 15 W/m2.°C. Thebottom surface of the brick is on an insulated stand. How much heat will have beenlost when the bricks cool to room temperature? How long will it take to lose halfthis amount, and what will the temperature at the geometric center of the stack beat this time?
