A) 288 m2

Explanation:
Ok so surface area is just adding up all the area of each faces. Just look at what I do below:

Area of the rectangular base:
10 • 6= 60

Area of the front triangle facing us:
1/2 • 12 • 10= 60
Multiply 60 by 2 cause there is still another similar triangle at the back- 60 • 2= 120

Area of the triangle facing right:
1/2 • 8 • 6= 24
Multiply 25 by 2 case there is still another similar triangle facing on other side(left)
24 • 2= 48

Add them all up together
60 + 120 + 48= 228

MARK ME BRAINLIEST TYSM
have a nice day/night! :DD
