I am solving following problem:
The problem states that on figure 1 there is shown a cube with three facets on which there is drawn three section(length). This cube was put on other facet and turned such that there is also shown these three length on one cube from list of cubes which are drawn below.our task is find which one is this cube?please help i think that D,E,and C is not, in my point of view it must be A but not sure.
$A$ is incorrect. Pretend you are standing on the line segment which touches a corner of the cube. Orient yourself so you are facing the this corner. Then the line which touches the side is to your left, but on $A$ it is to the right. So the answer can't be $A.$
The answer is $B.$ See if once you know the answer you have an easier time about the spacial reasoning.
