Surface area Composite 3-D figures practice seventh grade use the image to answer the question the image looks like a house at the top slant on the right is 20 M the side of the right is 8N the bottom is 10 M inside is 1230. What is the total surface of this?

Answer 1

To find the total surface area of this composite 3D figure, we need to find the surface area of each individual component and then add them all together.

The total surface area can be divided into 5 parts:
1. Front and back faces: 20m x 8m = 160 square meters
2. Left and right side faces: 20m x 10m = 200 square meters
3. Top face: 8m x 10m = 80 square meters
4. Bottom face: 8m x 10m = 80 square meters
5. Inside: 1230 square meters

Adding up all the individual surface areas:
160 + 200 + 80 + 80 + 1230 = 1750 square meters

Therefore, the total surface area of this composite 3D figure is 1750 square meters.
