![]() ![]() 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. 16 Mathematics Stage 5 Lesson 3 Designing a dog kennel Task 7 This is Annie. If your measurements are in different units, convert each measurement to the same unit first, then use the formulas below to solve. WooTube Example of Surface Area of a Triangular Prism Easier Activity Investigate area of 2D shapes: Extension Activity Geometric Solids. When calculating surface area, taking all measurements using the same unit of measure, such as inches or feet, is important. Solution: From the image, we can observe that the side lengths of the triangle are a 5 cm, b 6 cm and c 5 cm. The formula for surface area of a triangular prism is actually a combination of the formulas for its triangular bases and rectangular sides. ![]() ![]() Total surface area is the area of the whole object, including the curved surface, lateral faces, and the area of the base. Example 1: Find the surface area of the triangular prism with the measurements seen in the image. Lateral surface area is the area the polygon faces of the object, not including the top and bottom bases. A triangular prism has a triangular base with sides measuring 8 cm, 15 cm, and 17 cm. the volume of the triangular prism is 120cm3. Substitute the given values into the formula: V 1/2 × 4cm × 6cm × 10cm. An example of a curved region would be the cap area of a hemisphere or capsule. The formula for the volume (V) of a triangular prism is: V 1/2 × b × h × l. 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. ![]()
