Final answer:
Calculating the surface area of a building for painting requires exact dimensions, which the question does not provide. An example was provided assuming a flat roof and 10 ft high walls, resulting in a total surface area of 3100 sq ft for painting. More information is needed for a precise calculation.
Step-by-step explanation:
The question requires calculating the surface area of the outside of a building including its roof. The question is incomplete as it does not provide enough details about the shape or dimensions of the building beyond a single set of measurements (10 ft, 30 ft, 50 ft). Usually, for a rectangular prism, calculating the surface area involves finding the area of all the faces of the building: two sides, the front, the back, and the roof. However, without additional details, such as the height of the walls, the slope of the roof, or whether the building consists of multiple shapes, one cannot provide a specific answer. For a simple box-shaped building with these measurements as the base (50 ft by 30 ft) and a flat roof, the process would be to calculate the area of each face and sum them up.
If we assume a flat roof and the dimensions provided are for the base and height happens to be 10 ft, the surface area would be calculated as follows:
- Front and back (30 ft x 10 ft): 2 x 300 ft² = 600 ft²
- Sides (50 ft x 10 ft): 2 x 500 ft² = 1000 ft²
- Roof (50 ft x 30 ft): 1500 ft²
Adding these together would give us a total surface area of 3100 square feet that needs to be painted. However, this is just an example with made-up values, as the question does not provide exact dimensions for the walls and roof slope.
