This is a floor plan of a building that is 8m tall. It has a flat roof. What is the surface area of the building including the roof. The floor plan is starting from the left the side is 18m the bottom is 27m the right side is 22m. The top looks weird butits like three sections first a small sqsquare on the left with no measurment for the top or side the middle square has no measurment, and the right square which is the same size as the middle square but sticking out is 10m on the top .

help me

To find the surface area of the building, we need to calculate the area of each side and the roof separately, and then sum them up.

First, let's calculate the area of the four sides of the building:

1. Left side: The height of the building is given as 8m, and the length of the left side is 18m. So, the area of the left side is 8m * 18m = 144m².

2. Bottom side: The length of the bottom side is given as 27m, and since the building has a flat roof, the bottom side is also the same as the roof's length. Therefore, the area of the bottom side is 27m * 27m = 729m².

3. Right side: The height of the building is 8m, and the length of the right side is 22m. So, the area of the right side is 8m * 22m = 176m².

4. Top section: The top section of the building consists of three squares. Let's calculate the area of each square and add them together.

- The first small square on the left has no measurement given, so we cannot calculate its area. We will ignore it when calculating the total surface area.

- The middle square also has no measurement given, so we cannot calculate its area. We will also ignore it when calculating the total surface area.

- The right square, which is the same size as the middle square, has a length given as 10m on the top. We need to consider this square for the surface area calculation. The height of the building is 8m, and the length of the right square is 10m. So, the area of the right square is 8m * 10m = 80m².

Now, we can calculate the total surface area of the building by summing up the areas of the sides and the roof:

Total Surface Area = Left side + Bottom side + Right side + Top section
= 144m² + 729m² + 176m² + 80m²
= 1129m² + 256m²
= 1385m²

Therefore, the total surface area of the building, including the roof, is 1385m².
