Question 4 • Math 7 B (M12 25/26 S2)
Answer:
To find the surface area of a composite figure, first identify the individual three-dimensional shapes that make up the figure. Calculate the surface area of each individual shape separately (using a net or formulas). Add these surface areas together. Finally, subtract the area of any faces where the shapes meet or overlap, because those surfaces are no longer on the outside of the composite figure.
