The answer is <span>A) 472m^2; 486 m^2. </span> Let a, b, and c be the sides of the base and h be the height of the prism a = 2 m b = 7 m c = 7.28 m h = 29 m
The lateral surface area is: LA = a*h + b*h + c*h = h * (a + b + c) LA = 29 * (2 + 7 + 7.28) = 29 * 16.28 ≈ 472 m²
The surface area is: SA = LA + 2 * 1/2 * a * b SA = 472 + 2 * 7 = 472 + 14 = 486 m²
