Question

The figure below is a net for a triangular prism. The dimensions of the net are a = 10 feet, b = 12 feet, c = 13 feet, d = 11 feet, and e = 9 feet. What is the surface area of the triangular prism?

Answer 1

To find the surface area of a triangular prism, calculate the areas of the triangular and rectangular faces and add them up.

Step-by-step explanation:

To find the surface area of a triangular prism, we need to find the areas of all the faces and then add them up. The triangular prism has two triangular faces and three rectangular faces.

The formula to find the area of a triangle is:

Area = 0.5 * base * height

Given the dimensions of the net, we can calculate the areas of the two triangular faces using the formula. Then, we can calculate the areas of the three rectangular faces using the formula:

Area = length * width

Add up all the areas to find the total surface area of the triangular prism.
