The lateral area of a prism or pyramid is the combined area of its lateral faces. Similarly, the lateral area of a cylinder or cone is the area of its lateral surface. Examples: Given a bedroom in the shape of a rectangular prism, the lateral area is the area of the four walls.
Find the lateral area and surface area of an equilateral triangle base right prism with base edge 5 and height 9. 3. A rectangular prism is 12 cm long, 10 cm wide, and 6 cm high. Find the surface area of the prism. [A] 28 cm. 2 [B] 504 cm. 2.
Find the surface area of the following composite shape: Step 1: Work out which sides are facing outwards (these ones count as the total surface area). For the cube at the top, all sides except the bottom side are facing outward, so 5 faces are counted. For the cuboid, 5 full faces are facing outwards, and part of the top face. We can calculate
PowerPoint Presentation. Surface Areas of Prisms and Cylinders. Objective – Find the surface area of prisms and cylinders. Types of Prisms. Formulas You Need to Remember: Area of a Triangle → A = bh ÷ 2. Area of Parallelogram → A =bh. Area of Trapezoid → A = h(b1 + b2) ÷ 2. Key Concept(s): • Lateral Area and Surface Area of a Prism.
