Using the results from part D and the dimensions of the other surfaces, find the surface area of the outside of the doghouse. Be sure to include the bottom surface in your calculation. this was d Wendell plans to paint the doghouse after it’s built. He wants to know what the surface area of the outside of the doghouse will be. To find the surface area, first break up any composite shapes into rectangles and triangles. Which shape is considered a composite shape? When the shape is decomposed, what are the dimensions of the resulting shapes necessary for finding surface area?
