D. 336 ft²

Explanation:

There are 2 triangles of the same dimensions and 3 rectangles of different dimensions

✔️Area of the two triangles with the following dimensions:

b = 8 ft

h = 6 ft

Area of the two triangles = 2(bh)/2

= 2(8*6)/2

= 48 ft²

✔️Area of the rectangle with the following dimensions:

length = 12 ft

width = 10 ft

Area = length*width = 12*10

= 120 ft²

✔️Area of the rectangle with the following dimensions:

length = 12 ft

width = 8 ft

Area = length*width = 12*8

= 96 ft²

✔️Area of the rectangle with the following dimensions:

length = 12 ft

width = 6 ft

Area = length*width = 12*6

= 72 ft²

✅Total surface area of the object = 48 + 120 + 96 + 72 = 336 ft²
