The 3D figure shows the view of an object. Identify the correct view looking in the direction of arrow, amongst the answer figures.
Show Hint
Look along the shorter horizontal direction (arrow) and compare the widths of the base slab, the middle slab and the stepped block; all start at the same left edge.
The arrow looks at the long left-front face. In the elevation we see the length of that face from left to right. The object is a thin base slab (longest), a thinner middle slab that starts at the same left edge but is only about 0.6 of the base length, and a stepped block standing on the middle slab. The block is as long as the middle slab; its left part is the tallest and its right part is a lower step. In the elevation: the bottom strip is the base slab (full length); above it is the middle strip, about 0.6 of the length and flush with the left end; on top of it the block shows a tall part on the left (about two thirds of its length) and a lower step on the right, ending at the same right edge as the middle strip. Option (2) gives the base and the middle slab the same length, which is wrong; option (3) adds an extra square that is not present in this view; option (4) shows a plain rectangle without the step. Option (1) is correct. Answer: (1) the first answer figure
