Answer:
The surface area of the triangular prism is .
Step-by-step explanation:
The surface area of any prism is the total area of all its sides and faces. A triangular prism has three rectangular sides and two triangular faces.
An equilateral triangle is a triangle with all three sides of equal length.
To find the surface area, the area of each face is calculated and then add these areas together.
The formula is used to find the area of the triangular faces, where A = area, b = base, and h = height.
The formula is used to find the area of the three rectangular side faces, where A = area, l = length, and w = width.
The surface area of the triangular faces is:
The surface area of the three rectangular side faces is:
The surface area of the triangular prism is .
