Use the image to answer the question what Is the surface area of the triangular prism 12yd 13yd 5yd 11yd
The surface area of a triangular prism is calculated by adding the areas of the two triangular bases and the three rectangular faces.
The base of the triangle is 12yd and the height is 13yd. The area of one triangular base is 1/2 * base * height = 1/2 * 12yd * 13yd = 78 square yards.
The other triangular base will have the same area, so combined they will be 2 * 78 = 156 square yards.
The rectangular faces will have the dimensions 12yd x 11yd, 12yd x 11yd, and 13yd x 5yd. The area of each rectangle is length x width, so for the first two rectangles, the area will be 12yd * 11yd = 132 square yards, and for the last rectangle, the area will be 13yd * 5yd = 65 square yards.
The total surface area of the triangular prism is the sum of the areas of the two triangular bases and the three rectangular faces, which is 156 + 132 + 132 + 65 + 65 = 550 square yards.
Therefore, the surface area of the triangular prism is 550 square yards.
