Explanation
The correct answer is (B).
When you look at the shape from above or below, you will see a shadow identical to image B.
When you look at the shape from the side, you will see a shadow in the form of a dark square with lit triangles in it (B.N. the lit triangle are not identical to the one shown in the shape itself!).
Explanation
When looking from above, height doesn’t matter so the simplest thing to do is work out the outline of the shape. Once you have this you can see that it must be A which is a triangle with a kind of jagged edge.
Explanation
The easiest approach is to start as close to the mirror line as possible and work further away. You can see in this case that there are two circles slightly on top of each other so the answer must be A or D. If you assess the positioning of the outer circles, you can see the answer must be A.
Explanation
There are 6 blocks of 5-cube inverted pillars. Total 6X5=30. 6 blocks of 3-cube inverted pillars. Total 6X3=18. 4 blocks of 1-cube inverted pillars. Total 1X4=4. Grand total: 30+18+4=52.
Explanation
To get the answer you need to fold the cube together in your mind. Doing this, you can see that the 3 circles and the square will be adjacent and there will be a blank square adjacent to both of them.
Explanation
is to adjust the eye to see the 3-dimensional cube as a flat 2-dimensional geometrical composite. The outer figure has 6 sides, and thus a hexagon is definitely present.
Now, even though the sides are made up of squares if the figure were viewed as a 3-dimensional cube, here the ask is to check it in 2-dimensional form. So, apart from the outer hexagon we are left with 3 basic rhombuses (or diamonds). Hence the answer.
Explanation
You can see that the two large blocks are adjacent which rules out B. The thinner block sits inside the larger block which rules out A and C so the answer must be B.
