Isosceles triangle: two equal sides. We have the following relationship: root (32) = root (L ^ 2 + L ^ 2) root (32) = root (2L ^ 2) root (32) = Lraiz (2) root (32) / root (2) = L The surface area is: Area of the base and top: A1 = (1/2) * (root (32) / root (2)) * (root (32) / root (2)) A1 = (1/2) * (32/2) A1 = (1/2) * (16) A1 = 8 Area of the rectangles of equal sides: A2 = (root (32) / root (2)) * (6) A2 = 24 Rectangle area of different side: A3 = (root (32)) * (6) A3 = 33.9411255 The area is: A = 2 * A1 + 2 * A2 + A3 A = 2 * (8) + 2 * (24) + (33.9411255) A = 97.9411255 Round to the nearest tenth: A = 97.9 cm Answer: The surface area of the triangular prism is: A = 97.9 cm
Explanation: First, multiply 1.5 by 1.2 to get the area of the rectangle in METERS, which is 1.8. Since the question is asking for the area in CENTIMETERS, multiply 1.8 by 100 (because 1 meter=100 centimeters) to get 180cm^2.
