Two rooms, each a cube 4 m per side, share a 12-cm thick brick wall. Because of a number of 100-W lightbulbs in one room, the air is at 30 deg C, while in the other room it is at 10 deg C. How many of the 100-W bulbs are needed to maintain the temperature difference across the wall? kbrick = 0.84 W/m.K Round your answer to 2 decimal places.
