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!
