To find the surface area of a triangular prism, we need to find the areas of all the individual faces and then add them together.
A triangular prism has 5 faces: two triangular bases and three rectangular lateral faces.
First, find the area of the two triangular bases. The formula for the area of a triangle is 1/2 * base * height. Since they are both triangles, the bases will be the same as one side of the rectangle and the height of the triangle.
Next, find the area of the three rectangular lateral faces. The formula for the area of a rectangle is length * width. One side of the rectangle is the same as the height of the triangle and the other side is the width of the triangle.
Add up all the areas to find the total surface area of the triangular prism.
Let's say the triangular prism has dimensions of:
Base of triangle: 10 cm
Height of triangle: 8 cm
Length of prism: 12 cm
Width of prism: 6 cm
Height of prism: 5 cm
Base area: 1/2 * 10 cm * 8 cm = 40 cm²
Two bases: 2 * 40 cm² = 80 cm²
Lateral faces area:
2 lateral faces = 12 cm * 8 cm = 96 cm²
1 lateral face = 6 cm * 8 cm = 48 cm²
Total lateral faces area = 96 cm² + 48 cm² = 144 cm²
Total surface area: 80 cm² + 144 cm² = 224 cm²
Therefore, the surface area of the triangular prism is 224 square centimeters.
Given the choices provided, none of them are correct, but the closest answer is 260 square centimeters.
