Answer:
The correct answer is option d. 576 ft^2
Step-by-step explanation:
From the figure we can see that a prism
<u>To find the surface area</u>
Surface area = Base area + area of 2 triangles + Two side area
Base area = length * breadth = 15 * 12 = 180 ft^2
Area of triangle = bh/2 = (12 * 8)/2 = 48 ft^2
Area of two triangle = 48 * 2 = 96 ft^2
Area of one side = 15 * 10 = 150 ft^2
Area of two side = 2 * 150 = 300 ft^2
Surface area = 180 + 96 + 300 = 576 ft^2
The correct answer is option d. 576 ft^2
