Cube Questions and Answers
Definition of Cube
A cube is a three-dimensional shape, which has six equal squares. A Cube and dice have total of 6 faces, 8 vertices, and 12 edges. The 3 visible sides of cube at the same time can never be on the opposite side of each other. Below is the figure of a cube.
According to the figure above, the six faces in the cube are– AFEG, ABHF, GEDC, DEFH, ABCG, and BHDC and. By observing the cube it is concluded that:
- There will always be contradictory faces in the cube. For example, AFEG is opposite to BHDC, AGCB is opposite to DHEF, and similarly others.
- GEDC is the upper side/face of the cube, and ABHF is the bottom side of the cube.
- Four faces will always be there, which will be together with one face.
- If there are two CUBES that have one digit as common with the same surface, then other surfaces digits will be contradictory to each one. The picture below shows that 4 is common in both the cubes with same surface. Therefore, 5 will be opposite to 2 and 3 will be opposite to 1.
- If a cube has 2 digits common then the remaining numbers will be opposite to each other and the number opposite of common digits cannot be determined. The figure below makes it clear that 6 and 2 are common numbers with different surfaces. Thus, 3 will be opposite to 5. Now the question is what will be the opposite of 2 and 6, then answer will not be evaluated since there surfaces are not similar.
- If there are two CUBES having one digit common with different surfaces, then rotate it in the clockwise direction to get the opposite side. The below-mentioned pictures show 2 figures X and Y. Looking at figure X, we can see that if we rotate 2 we first see 6 then 5 comes. Hence 6 is opposite to 4. In figure Y if we rotate 2, we first see 4 then comes 1; therefore, 1 is opposite to 5.
