A laser scan of a pavilion's roof is performed, and the point cloud data is obtained. The roof of the pavilion has a triangular cross-section. The following points have been extracted from the scan data for analysis: Points: Point A: (0,0,3) Point B: (10,0,3) Point C: (0,5,4) Point D: (10,5,4) Deliverables: 1. Detailed calculations of the surface area of the pavilion's roof. 2. Detailed calculations of the volume of the pavilion. 3. A report on the planarity assessment of the roof, including the fitted plane equation and the deviations of each point.
