For a particular timber species the form factor (F) varies linearly with the diameter at breast height (D). When D = 30 cm, F = 0.45. Assuming the relationship passes through the origin, determine the total timber volume (in cubic metres, rounded to the nearest whole number) that can be obtained from a stand of 120 trees, each having D = 45 cm and a height of 20 m. Use the volume formula \(V = F \times \frac{\pi}{4} D^{2} H\) where D is in metres.
