(II) Two rooms, each a cube 4.0 m per side, share a 14-cm thick brick wall. Because of a number of 100-W lightbulbs in one room, the air is at 30$^\circ$C, while in the other room it is at 10$^\circ$C. How many of the 100-W bulbs are needed to maintain the temperature difference across the wall?

(II) Two rooms, each a cube 4.0 $\mathrm{m}$ per side, share a 12 -cm-thick brick wall. Because of a number of $100 . \mathrm{W}$ lightbulbs in one room, the air is at $30^{\circ} \mathrm{C}$ , while in the other room it is at $10^{\circ} \mathrm{C}$ . How many of the $100-\mathrm{W}$ bulbs are needed to maintain the temperature difference across the wall?
