Section 12.2 Surface Areas of Prisms and Cylinders 645 EEssential Questionssential Question How can you fi nd the surface area of a prism or a cylinder? Recall that the surface area of a polyhedron is the sum of the areas of its faces. The lateral area of a polyhedron is the sum of the areas of its lateral faces. Finding a Formula for Surface Area
Another way to calculate the lateral area for a right prism is: lateral area = perimeter • height; Another way to write the surface area for a right prism is: SA = perimeter • height + 2 • area of base; Volume of a Prism. Theorem: The volume of a prism is V = Bh, where B is the area of the base and h is the prism’s height. For a ...
Surface Area of a Right Prism. Theorem : The surface area S of a right prism can be found using the formula . S = 2B + Ph. where B is the area of a base, P is the perimeter of a base, and h is the height. Finding the Surface Area of a Cylinder. A cylinder is a solid with congruent circular bases that lie in parallel planes.
Find the lateral area and surface area of each figure. Round your answers to the nearest tenth, if necessary. 13) A hexagonal prism 6 ft tall with a regular base measuring 9 ft on each edge and an apothem of length 7.8 ft. 324 ft²; 745.2 ft² 14) A prism 2 m tall. The base is a trapezoid whose parallel sides measure 7 m and 3 m.
Lesson 11-2 Surface Areas of Prisms and Cylinders 611 Finding Surface Area of a Cylinder The radius of the base of a cylinder is 4 in. and its height is 6 in. Find the surface area of the cylinder in terms of p. S.A. =L.A. +2B Use the formula for surface area of a cylinder. =2prh +2(pr2) Substitute the formulas for lateral area and area of a ...
Total Surface Area: The total surface area of a prism or pyramid is the combined area of its lateral faces and its base(s). Similarly, the total surface area of a cylinder or cone is the combined area of its lateral surface and its base(s). The total surface area of a solid can also be thought of as the area of the solid’s net.
There are both rectangular and triangular prisms. To find the surface area of a prism (or any other geometric solid) we open the solid like a carton box and flatten it out to find all included geometric forms. ... Find the surface area of a cylinder with the radius 4 and height 8. Find the volume of a cone with height 5 and the radius 3. Do ...
Take advantage of this huge ensemble of 50+ worksheets on the surface area of prisms and cylinders and help students of grade 6, grade 7, grade 8, and high school ease into the concept. The surface area of a cylinder is the sum of the areas of its curved surface and bases; the surface area of a prism is the sum of the areas of its bases and faces.
Finding the Surface Area of a Prism Find the surface area of a right rectangular prism with a height of 8 inches, a length of 3 inches, and a width of 5 inches. SOLUTION Begin by sketching the prism, as shown. The prism has 6 faces, two of each of the following: The surface area of the prism is S= 2(40) + 2(24) + 2(15) = 158 in.2 EXAMPLE 1 ...
