Geometry

Question Analysis:
This question deals with a non-rectangular, non-triangular prism, where the base is a trapezoid.
The main focus is applying lateral surface area using the sides of the trapezoid and prism height.

Key Concept Explanation:
Lateral surface area is the sum of the areas of rectangles formed by each side of the trapezoid base × prism height.
We need all four sides of the trapezoid.

Step-by-Step Solution:
Base sides: 6 cm, 10 cm, 5 cm, 5 cm
Prism height = 8 cm
Lateral area = (6 + 10 + 5 + 5) × 8 = 26 × 8 = 208 cm²
Correction: Actually, wait — 6 + 1...
