The formula to find the area of a triangular prism is 12 bhl, where b represents the length of the base of the triangle, h is the height of the triangle, and l is the length between the triangles.p perimeter of a base. h height of the prism. Try this Change the height and dimensions of the triangular prism by dragging the orange dots. Note how the surface area is calculated. A right prism is composed of a set of flat surfaces. The two base are congruent polygons. The lateral faces (or sides) are rectangles. how to find total area of a right triangular prism

Find the area of all three rectangles and both bases to get that prism's total surface area. Use length times width, (l)(w), to calculate a rectangular face on the prism. Multiply the result by the number of faces your prism
