Surface Area of Composite Figures Worksheets
The shapes that we see around us are often a combination of two or more shapes. Count on our surface area of composite figures worksheets for an adequate practice in finding the surface area of non-overlapping rectangular prisms, compound shapes made of cubes, cones, cylinders, hemispheres, prisms, pyramids, and circumscribed figures with solids within solids. Follow the step-by-step process of decomposing, finding the SA of individual shapes, adding their surface areas, and subtracting the area of common parts and you will be good to go! Our free printable samples are a compulsive try for your grade 6, grade 7, and grade 8 students!
Grade 6 and grade 7 students decompose the L-shaped rectangular prisms in these printable surface area of non-overlapping rectangular prism worksheets, add the SA of each solid shape and minus the area of the attached parts.
Whether it is a cone with a hemispherical top or a cylinder with a conical cap, these surface area of composite figure pdfs have them all. Split the shapes, add the surface areas, subtract the common side and that's it!
A treasure chest or an hourglass, what do these shapes remind you of? With many such interesting shapes for your 7th grade and 8th grade students to determine the surface area of compound solids, these pdf worksheets are a class apart.
Break down the compound figures into independent 3D shapes: cubes, cones, cylinders, hemispheres, prisms, pyramids, find the SA of each, then sum up the SAs together paying special attention to the common area, and subtracting it to compute the SA of the compound shapes.
Grade 8 students use these printable exercises, and begin finding the surface area of shapes that are circumscribed within other shapes by finding the SA of the outer solid and subtracting the SA of the shape within.
