Example 1įind the surface area of a closed box with base width 3 cm, base length 5 cm and height 4 cm. To find the surface area of a rectangular prism or a box, we first flatten it creating the net, and then work out the total surface area by adding the areas of the individual rectangles. The surface area of a prism is the sum of the areas of its faces. Base is a rectangle, so its perimeter is P 2l +. Source: Australian Curriculum, Assessment and Reporting Authority (ACARA) The bases are the triangles at the front and back of the prism. Total Surface Area (T.S.A) = 2 × Area of triangular base + L.S.A.Solve problems involving the surface area and volume of right prisms (ACMMG218)Ĭalculate the surface area and volume of cylinders and solve related problems (ACMMG217) Lateral (Curved) Surface Area (L.S.A) = Perimeter of triangular base × length The base of the triangular prism is a triangle. The lateral surface is the total area of the lateral faces (The length times the perimeter of base) and volume is equal to the product of base area and its length or height.Īrea of triangular base = Area of ΔABC or Area of ΔEFG A very common example of a triangular prism is the well-known chocolate box. The length or height ( AE, BF, CG ) is the perpendicular distance between the bases.

Online calculators and formulas for a surface area and other geometry problems. Calculate the unknown defining side lengths, circumferences, volumes or radii of a various geometric shapes with any 2 known variables. Answer: The surface area of the equilateral triangular prism is 180 squared units. Calculator online for a the surface area of a capsule, cone, conical frustum, cube, cylinder, hemisphere, square pyramid, rectangular prism, triangular prism, sphere, or spherical cap. The surface area of an equilateral triangular prism 2 × 60 + 3 × 20. The intersection of lateral faces is lateral edges. The surface area of an equilateral triangular prism Area of the top and base triangles + Area of the three rectangular faces. The lateral faces (AEFB, AEGC and BCGF), are rectangles formed by joining corresponding vertices of the bases. Area of each triangle is called base area or area of the base. These steps are represented by the formula, where equals the lateral area of the prism and equals the area of one base.

Finally, you need to add these two areas together to find the total surface area. Therefore, the formula for the surface area of a triangular prism is. In the case of a triangular prism, two congruent and parallel triangles ABC and EFG are called the base of the prism. Lastly, all youll have do to find the total surface area of a triangular prism is to add together the areas of its sides, which gives you 260 c m 2 260cm2 260. To find the surface area of triangular prism, you first need to find the area of the lateral sides, then you need to find the area of the bases. one rectangle with length l and breadth b and two rectangles with length l and breadth s.
