a. Area of A = 20 ft²
Area of B = 16 ft²
Area of C = 12 ft²
Area of A = 24 ft²
b. The surface area of the triangular prism = 96 ft².
How to Find the Surface Area of a Right Triangular Prism?
The surface area of the triangular prism given in the diagram = area of A + B + C + D.
a.
Area of A (rectangle) = (length)(width) = (10)(2) = 20 ft²
Area of B (rectangle) = (length)(width) = (8)(2) = 16 ft²
Area of C (rectangle) = (length)(width) = (6)(2) = 12 ft²
Area of A (rectangle) = 1/2(base)(height) = 1/2(6)(8) = 24 ft²
b. The surface area of the triangular prism = 20 + 16 + 12 + 2(24) = 96 ft².
