Answer:
17.3 ft
Step-by-step explanation:
To find this, we have to add up the areas of the 3 rectangular faces and two triangular faces.
Let's find the areas of the triangles first
We just have to multiply base and height then divide it by 2
2 x 1 = 2
2 ÷ 2 = 1
Since there are two identical triangular faces, multiply that number by 2
1 x 2 = 2
Now let's find all the areas of the rectangular faces with l x w
1 x 3 = 3
2 x 3 = 6
3 x 2.2 = 6.6
6.6 + 6 + 3 = 15.3
Now add up the areas
15.3 + 2 = 17.3
