Answer:
First we need to convert those feet into inches.
0.5 x 12 = 6 inches
1.5 x 12 = 18 inches
4 inches is just 4 inches
Now we just find the surface area:
6 x 4 = 24
24 x 2 = 48
18 x 4 = 72
72 x 2 = 144
6 x 18 = 108
108 x 2 = 216
Now lets add all the given areas:
48 + 144 + 216 = 408 square inches (just do the number since they tell you not to use the unit)
