A cake recipe suggests a cooking temperature of 325 degree Fahrenheit if the batter is less than one inch thick and 350F if the batter is more than one inch thick. If the cake batter has a volume of 100 in^3 and your cake pan is 9inches by 11 inches, what does the oven need to set at if the oven temperature settings are in degrees Celsius? (round to nearest whole number)

The first step is finding the height of the cake. The formula for the volume of a box: Volume = length x width x height. So given the volume and length and width: 100 = 9 x 11 x h. 100=99h and solve for h. h = 1.01 inches so the batter is more than one inch thick. That means that the matter needs to be baked at 350 degrees Fahrenheit. The formula to convert from Fahrenheit to Celsius: T (C) = (T (F) - 32) x (5/9). So (350-32) x (5/9) = 176.667. Rounded to the nearest whole number is 177 degrees celsius.
