Question
A hexagonal prism has a base edge of 4 cm and a height
of 10 cm. What is the total surface area of the prism?Solution
Area of one hexagonal base = (6√3/4) * (a²) Where a = 4 cm: = (3√3/2) * (4²) = (3√3/2) * 16 = 24√3 cm². Total area of the two bases = 2 * 24√3 = 48√3 cm². Lateral surface area = perimeter of the base * height = (6 * 4) * 10 = 240 cm². Total surface area = Lateral surface area + Total area of bases = 240 + 48√3 ≈ 240 + 83.14 = 323.14 cm². Correct option: a) 323.14 cm²
