Question

Use the net to find the surface area of the triangu

Answer 1

To find the surface area of a triangular prism, calculate the area of the base triangle and the lateral area, then sum them up.

Step-by-step explanation:

To find the surface area of a triangular prism, you first need to find the area of the triangular base and the lateral area. Then, you can add these two areas together to get the total surface area.

1. Find the area of the triangular base by using the formula: base * height / 2.
2. Next, find the lateral area by multiplying the perimeter of the base by the height of the prism.
3. Add the area of the base and the lateral area together to find the surface area.

For example, let's say the base of the triangular prism has a base of 6 units and a height of 4 units. The perimeter of the base is 18 units and the height of the prism is 8 units. The area of the base is 6 * 4 / 2 = 12 square units. The lateral area is 18 * 8 = 144 square units. Therefore, the surface area is 12 + 144 = 156 square units.
