Question Analysis:
This question tests the ability to find the total surface area of a prism with a trapezoidal base.
The main focus is using both the trapezoid area formula and calculating the lateral surface area.

Key Concept Explanation:
Area of trapezoid = ½ × (Base1 + Base2) × height
Total Surface Area = 2 × Base Area + Lateral Area
Lateral Area = Perimeter of base × prism height

Step-by-Step Solution:
Trapezoid area = ½ × (6 + 10) × 4 = ½ × 16 × 4 = 32 cm²
Perimeter of base = 5 + 5 + 6 + 10 = 26 cm
Lateral Area = 26 × 8 = 208
Total surface are...
