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
The arrow looks at the left face, so draw the left side elevation: the back of the object is at the left of the view and the front is at the right. Place each block by its depth and height.
The arrow points at the left face of the object, so we need the side elevation seen from the left. In that view the depth of the object runs across the picture: the back is at the left and the front is at the right. Depth and height of the main solid (1 unit = one level): the tall block is 4 units high and fills the back two depth units; the second step is 2 units high and fills the next depth unit; the lowest step is 1 unit high and fills the front depth unit. The outline therefore falls from left to right in three stages: 4, 2, 1. The thin tall slab on top of the tall block stands at the front end of the block top (flush with the front face of the block) and is one depth unit deep. In the view it is a narrow rectangle above the right end of the tall column, about 1.5 units high. The small cube and the box that stick out in front of the tall block are one depth unit deep and are raised about half a unit above the top of the second step. Seen from the left, the cube is a square drawn over the second-step column with a narrow gap (half a unit) between its lower edge and the top of the step. Check the answer figures: option (2) puts the thin slab at the far left (back) end, option (3) puts it in the middle of the tall column, and option (4) removes the gap by placing the square directly on the step. Only option (1) has the thin slab at the right end of the tall column and the square over the second step with a gap below it. Answer: (1) the first answer figure
