Length of long wall = 3.5+3.5+0.30+0.30×2 = 15.2m

Length of short wall = 3×4.30 = 12.9m

Total length of wall = 28.1m

Now we have calculated deduction of Windows, Doors and Ventilators:

Doors = 2.1×1.05×0.30(2) = 1.32 cum

Windows = 1.2×1.2×0.30(2) = 0.86 cum

D.V = 1.5×0.45×0.30(2) = 0.28 cum

W.V = 1.20×0.45×0.30(2) = 0.32 cum

Total deduction = 2.78 cum
