-4 + 4 = 0
0 + 20 = 20
20 + 4 = 24 degrees celcius

The total surface area for the figure shown will be calculated as follows: sa is the total area of every surface in the figure, thus we shall have: sa=(20×10)+2×(9×20)+(12×10)+2×(15×8)+(15×10)+(24×10)+(10×8)sa=200+2(180)+120+2(120)+150+240+80sa=200+360+120+240+150+240+80sa=1390 in²
