To find the surface area of the letter C sculpture, we need to calculate the surface area of each individual face and then add them together.
1. Top face: 10 ft x 1 ft = 10 ft²
2. Bottom face: 10 ft x 1 ft = 10 ft²
3. Front face: 15 ft x 1 ft = 15 ft²
4. Back face: 15 ft x 1 ft = 15 ft²
5. Left side face: 15 ft x 4 ft = 60 ft²
6. Right side face: 4 ft x 7 ft = 28 ft²
Adding up all the surface areas:
10 ft² + 10 ft² + 15 ft² + 15 ft² + 60 ft² + 28 ft² = 138 ft²
Therefore, the surface area of the letter C sculpture is 138 ft².
