The surface area = The area of the two bases + the area of the lateral surface
The area of 1 base = 24 mm², so the area of two is 48 mm².
The area of the lateral surface = the perimeter of the base × the height. The perimeter = 22 mm. The height = 5 mm. Thus the lateral surface area is 110 mm².

The area of 1 base = 24 mm², so the area of two is 48 mm².
The area of the lateral surface = the perimeter of the base × the height. The perimeter = 22 mm. The height = 5 mm. Thus the lateral surface area is 110 mm².
The final answer is 158mm to the power of 2</span>
