Answer: 3173 mm² (Answer C)
Area of the bottom triangle = 1/2 x base x height
Area of the bottom triangle = 1/2 x 19 x 23 = 218.5mm²
Area of the top triangle = area of the bottom triangle
Area of the top triangle = 218.5mm²
Area of the 3 side rectangles = (23 x 38) + (19 x 38) + (30 x 38)
Area of the 3 side rectangles = 2736 mm²
Total Surface area = 218.5 + 218.5 + 2736 = 3173 mm²
