Answer: 144
Step-by-step explanation:
You add up the area of each side
the two triangular sides- A=BH/2 3 times 4 divided by 2 so 6 but there are two triangles so you multiply by two so 12
the bottom rectangle- A=LW 4 times 11 so 44
the top rectangle- A=LW 5 times 11 so 55
the back rectangle- A=LW 3 times 11 so 33
12+44+55+33=144
