Use the image as a guide for understanding the formula. There is a different surface area formula for each shape. The calculator above can easily find the surface area for a shape, but you can also find it using a formula. If your measurements are in different units, convert each measurement to the same unit first, then use the formulas below to solve. We know that (a + b + c) is the perimeter of the base (triangle). When calculating surface area, taking all measurements using the same unit of measure, such as inches or feet, is important. Lateral Surface Area of Triangular Prism Calculator. Total surface area is the area of the whole object, including the curved surface, lateral faces, and the area of the base. Lateral surface area is the area the polygon faces of the object, not including the top and bottom bases. Calculate the angle of refraction in glass if the refractive index of. The total surface area of a triangular prism is the sum of the lateral surface area and twice the area of the triangular base. A ray of light is incident on a glass slab making an angle of 60o with the surface. The volume is equal to the product of the length of the prism and the area of the triangular base. An example of a curved region would be the cap area of a hemisphere or capsule. The triangular prism is said to be uniform if the triangles at the base are equilateral, and the sides are squares. Online calculator to calculate the surface. There are several types of surface area: curved surface area, lateral surface area, and total surface area.Ĭurved surface area is the area of the curved regions of an object. Surface Area Triangular Prism CalculatorA collection of Corbettmaths Practice Question Booklets on Surface Area. Example: What is the volume of a prism where the base area is 25 m 2 and which is 12 m long: Volume Area × Length.
