First, let's calculate the area of the roof. Since the top portion of the bird house is a triangular prism, the area of the triangular roof can be calculated using the formula:
Area of triangle = 1/2 * base * height
Area = 1/2 * 4.0m * 2.5m = 5 square meters
Next, let's calculate the area of the floor. The floor of the bird house is also a rectangle, so the area can be calculated as:
Area of rectangle = length * width
Area = 5.0m * 2.5m = 12.5 square meters
Adding the area of the roof and floor together:
5 square meters (roof) + 12.5 square meters (floor) = 17.5 square meters
Therefore, the correct answer is not provided.
The top portion of a bird house is in the shape of a triangular prism. How many square meters of wood is needed for the roof and floor? The dimensions are as follows: h=2.5 meters, b=4.0 meters, l=5.0 meters, and s=2.5 meters.
A. 55 square meters
B. 19 square meters
C. 45 square meters
D. 48 square meters
