Answer:

area = 186.984

Step-by-step explanation:

The 3 rectangular surfaces are simply L * W of each so

left surface = 5.5 * 6.2 = 34.1

right surface = 5.5 * 8.5 = 46.75

bottom surface = 5.5 * 9.8 = 53.9

The front and back are the same so

front = 1/2 base * heigth = 1/2 * 9.8 * 5.33 = 26.117

front + back = 2 * 26.117 = 52.234

total = sum them all up = 34.1 + 46.75 + 53.9 + 52.234 = 186.984
