Question

How do you find the surface area of a composite figure?

Answer 1

1. unfold the composite shape into its net, which is a two dimensional composite figures.
2. Divide any composite faces on the net into triangles or quadrilaterals, as you do with other two-dimensional composite figures.
3. calculate the area of each simple shape found on the surface of the figure.
4. add all the areas from step 3 to find the surface area of the composite 3d shape.

Answer 2

Answer:

Sample response: First separate the composite into component figures. Then find the surface area of each figure. A two-dimensional net can be used to find the surface area. Add the surface areas of the components. Then, subtract or exclude the areas of the figures that are shared.
