![]() In surface area questions, we need to know all three side lengths of the triangle however we only need the base and the height to calculate the area of the triangle. Using the wrong measurements to work out the area of the triangle faces.To find surface area, work out the area of each face and add them together The area of the triangular cross-section is 10 mm². Volume and surface area are different things – volume tells us the space within the shape whereas surface area is the total area of the faces. Multiply the base by the height and divide by two, (5 × 4)/2 10. To calculate the volume, all you have to do is find the area of one of the triangular bases and multiply it by the height of the prism. Calculating volume instead of surface area Formula to Calculate Volume of a Triangular Prism.You can’t have some measurements in cm and some in mīe careful to apply the correct prism related formula to the correct question type. It depends on the data youre given as to how to proceed to determine both the lateral. The most general formula for the surface area of any prism is: Total area Lateral area + 2 × Base area. You need to make sure all measurements are in the same units before calculating volume.Į.g. The total surface area of a triangular prism is the sum of the areas of all its faces: the three lateral faces (rectangles) and two bases (triangles). Surface area is measured in units squared (e.g. ![]() You should always include units in your answer. ![]() Learn the formula, see an example, and find out the practical applications of this calculation. Step-by-step guide: Surface area of a triangular prism Use this calculator to easily calculate the volume of a triangular prism or tank from its length, base, and height in any metric system. Since it is an area, surface area is measured in square units (e.g. The triangular faces of a triangular prism are congruent (exactly the same) but, unless the triangle is an isosceles triangle or an equilateral triangle, the rectangles are all different. The lateral surface area is the total area of the rectangular sides For a triangular prism the top and the base are triangles and the lateral faces are rectangular sides. Lateral faces are all of the faces of an object excluding the top and the base. To work out the surface area of a triangular prism, we need to work out the area of each face and add them all together. The surface area of a triangular prism is the total area of all of the faces.
