Answer: A
Step-by-step explanation:
I'm assuming this is a right triangular prism.
The area of the two triangles at the front and back of the figure are (1/2)(10)(26), so the sum of their areas is (10)(26)=260.
The area of the back rectangle is 36(10)=360.
The area of the top rectangular face is (36)(28)=1008.
And finally, the area of the bottom rectangular face is (36)(26)=936.
So the total surface area is 1008 + 936 + 360 + 260 = 2564.
