Answer:
85.2 units^2
Step-by-step explanation:
So first we have to find the area of the two triangles:
A = 1/2*bh*2
A = 1/2*6*5.2*2
A = 31.2units^2
Now, find the area of the two rectangles on the sides:
A = lw*2
A = 6*3*2
A = 36units^2
Now, find the area of the bottom rectangle:
A = lw
A = 6*3
A = 18un^2 (un abbreviated for units)
Now add all of the areas:
Total Surface Area (TSA) = 31.2+36+18
TSA = 85.2un^2
