Answer:
C. 216
Step-by-step explanation:
Surface Area is the outside area of a shape
Area of the two triangles are
A = [tex]\frac{1}{2}[/tex]bh
But we don't need to divide the b x h by half because there is another triangle so
A = bh
A = 6 x 4
A = 24
Then the base square is A = bh
A = 6 x 12 = 72
Then the square is A = bh
A = 5 x 12
A = 60 and since there is another square on the other side we add another 60
60 + 60 + 72 + 24 = 216
