The wall of a house consists of three layers: a wooden outer wall with an R factor of 1.0, a 3in layer of fiberglass insulation with an R factor of 11, a a gypsum board inner wall with an R factor of .33 ( all R factors are in h* ft^2 * degreesF/Btu). When the temp is 68degreesF inside the house and -4.0degreesF outside, what is the rate of heat loss throug an 8ft by 15ft section of this wall.
