Final answer:
Without a description of the composite figure, the surface area cannot be calculated. Generally, the surface area of cubes is found using the formula SA = 6 × s² and that of triangles using Area = 1/2 × base × height. The total surface area is the sum of these individual areas.
Step-by-step explanation:
To find the surface area of the composite figure mentioned, we must first understand what the composite figure looks like and its dimensions. However, since the figure has not been described in the question, we cannot calculate the exact surface area without that information. If it consists of shapes like cubes and triangles, we would individually calculate the area of each face for the cubes and the area of the triangles and sum them up to find the total surface area.
Here's a general approach to calculating the surface area of composite figures consisting of cubes and triangles:
- For each cube, use the formula for the surface area (SA = 6 × s²) where 's' is the side of the cube.
- For each triangle, use the formula for the area (Area = 1/2 × base × height).
- Sum the areas of all the faces and triangles to find the total surface area.
To provide an answer to the specific question, additional information about the composite figure is needed.
