2) Question.

Referring of Fig.24.1,pick up the correct statement from the following: $\cdot$
Answer.
- 1
  
  The total length of centre line of four walls is 20m
- 2
  
  Length of long wall out-to-out is 6.80m
- 3
  
  Length of short walls in-to-in is 3.20m
- 4
  
  All the above
Answer: 4

Explanation:
3) Question.

In long and short wall method of estimation,the length of long wall is the centre to centre distance between the walls and
Answer.
- 1
  
  breadth of the wall
- 2
  
  half breadth of wall on each side
- 3
  
  one fourth breadth of wall on each side
- 4
  
  None of these
Answer: 2

Explanation:
In long wall and short wall method, the wall along the length of the room is considered to be long wall and the wall perpendicular to the length of the room is considered to be short wall.

Long wall length out-to-out = centre to centre length + half breadth on one side + half breadth on the other side
= centre to centre length + one breadth

Short wall length in-to-in = centre to centre length – one breadth
4) Question.

The centre line method is specially adopted for estimating
Answer.
- 1
  
  Hexagonal buildings
- 2
  
  Octagonal buildings
- 3
  
  Other geometrical shaped buildings
- 4
  
  All the above
Answer: 4
Explanation:
The Centre Line Method is generally adopted for estimating quantities in buildings where:
- The walls are of uniform thickness.
- The plan is symmetrical.
- There are many wall junctions, making long-wall and short-wall calculations tedious.
This method is particularly convenient for:
- Hexagonal buildings
- Octagonal buildings
- Other geometrical (polygonal or curved) shaped buildings
In these structures, measuring the total centre-line length of walls simplifies the estimation of excavation, concrete, brickwork, plastering, etc.
