Question figure shows 3D view of an object. Identify the most appropriate top view of the given 3D object looking in the direction of an arrow, from the given answers figures.
Show Hint
Looking straight down, the long block with the small bar on it, the house-shaped prism and the triangular prism appear as a rectangle with an inner bar, two squares and a triangle.
The arrow points vertically down, so the required view is the plan on the square base plate. The tall block is long in one direction, so it is a long rectangle. The small bar on its top appears as a narrow rectangle inside it. The house-shaped prism is seen from above as a rectangle split by the ridge line into two equal squares. It stands against one long side of the tall block, near the end nearest the viewer. The triangular prism stands further away on the base plate, beyond the house along both directions of the plate, and from above it appears as a triangle. Option 2 shows the long rectangle with the inner bar, the two squares below it near the left end and the triangle at the lower right. Option 3 has the same parts but laid out as a mirror arrangement, with the triangle on the wrong side of the house. Options 1 and 4 are elevations, not top views. Answer: (2) Option 2 figure
