Step-by-step explanation:
The surface area of right triangular prism is the sum of area of two base triangles and 3 area of side rectangles.
The area of base triangle is

where a is the length of the side of equilateral triangle. In your case, a=6 inches. Thus,

The area of side rectangle is

where h is the height of the rectangle. In your case, h=10 inches. Thus,

Hence, the surface area is
