A wall of width 300 mm contains two T junctions. The height of the wall is 3 m and total length of the central line is 150 m. Calculate the quantity of
the brick work (in cubic meter) using central line method. [Asked in SSC JE 2017]

1) 134.46

2) 134.73

3) 134.86

4) 135


The correct Answer Is

2) 134.73

I think as per center line method at two T joints the length of wall is deducted for half thickness of wall i.e. 150 mm, two joints so the total centre line length will reduced by 300 mm

Now total wall length as per center line will be 150 - 0.300 meter = 149.7 meter.

So total volume will be 149.7 X 3 X 0.3 = 134.73

Correct answer is 134.73 cum
