Triangular prisms have their own formula for finding surface area because they have two triangular faces opposite each other. The formula A=12bh is used to find the area of the top and bases triangular faces, where A = area, b = base, and h = height.
Answer: The height and the width is a number that would be multiplied by itself like 5x5=25. The answer to this question would be 12 as the width and the height.
