The measure of the total surface area occupied by the triangular based prism is defined as the surface area of a triangular prism. The surface area is normally measured in square units. The surface area of a triangular prism formula uses the values of base, height, sides and prism height to determine the SA of the triangle prism. If you think it is too long to remember the SA formula just find the area of all the shapes on it and add them together.

Generally, the surface area of a triangular prism formula is equal to twice the base area plus the perimeter of the base times the height or length of the solid. Use our online triangular prism calculator to find the surface area within a blink of eye.
