Let's break down the tasks from this image one by one.

6. Given is the illustrated slanted projection of a house:

a) Bestimmen Sie die Koordinaten der Punkte B, C, D, E, F, H und I.

• You need to find the coordinates of the following points based on the given diagram:

  • A is already given as (0 | -4 | 0).
  • K is at (-10 | 0 | 5).
  • G is at (-10 | 4 | 3).

  I will extract the coordinates of the remaining points (B, C, D, E, F, H, I) based on the 3D diagram using the given axes.

b) Das Dach soll eingedeckt werden. Welchen Inhalt hat die Dachfläche?

• The roof needs to be covered. We are asked to calculate the area of the roof.
  • The roof consists of two triangular faces (H, I, D, K) and (G, I, D, K), so we will calculate the areas of these triangles and sum them.

c) Das Haus soll verputzt werden. Wie groß ist die zu verputzende Außenfläche des Hauses?

• The house will be plastered. We need to calculate the total surface area that needs plastering, which includes the walls and the roof but not the base.

d) Welches Volumen hat das Haus?

• What is the volume of the house?
  • The house can be thought of as a prism with a rectangular base (A, B, E, F) and a triangular roof. We will calculate the volume by splitting it into these two sections.

e) Zwischen welchen der eingetragenen Punkte des Hauses liegt die längste Strecke? Wie lang ist diese Strecke?

• Between which of the labeled points lies the longest distance? We will calculate all distances between relevant points and determine the longest.

I'll start by determining the coordinates of the required points based on the diagram, which will help solve the subsequent questions. Let's calculate those coordinates first.Here are the coordinates for the points as requested:

• A: (0, -4, 0)
• B: (0, 0, 0)
• C: (-10, 0, 0)
• D: (-10, 0, 3)
• E: (0, -4, 3)
• F: (0, 0, 3)
• H: (-10, 0, 5)
• I: (-10, 0, 3)
• K: (-10, 0, 5)
• G: (-10, 4, 3)

These coordinates will help in solving the remaining sub-questions. Would you like me to proceed with calculating the roof area (part b), or do you have any specific questions?

Related Questions:

1. What is the area of each side of the house?
2. How do we calculate the surface area of a triangular face in 3D space?
3. What is the formula for the volume of a triangular prism?
4. How can we calculate the surface area of all the walls and roof combined?

Tip: When working with 3D geometry, visualize the shapes as combinations of familiar geometric forms like triangles, rectangles, and prisms.
